Answer» Given :- The present age of MOHAN's mother is FOUR times that of Mohan's age. Mohan's age ten years from now will be one THIRD of his mother's present age. To Find :- The present ages of Mohan and his mother. Solution :- Let the present age of Mohan be x and the present age of Mohan's mother be y. According to the question, CASE - 1 $\sf{y=<klux>4X</klux>}$ . . .(i) ____________________ CASE - 2 $\sf{x+10=\dfrac{1}{3}\times (y+10) }$ Substituting value of y from (i) :- $\longmapsto \sf{x+10=\dfrac{1}{3}\times (4x+10) }$ $\longmapsto \sf{3(x+10)=4x+10}$ $\longmapsto \sf{3x+30=4x+10}$ $\longmapsto \sf{30-10=4x-3x}$ $\longmapsto \sf{20=x}$ ____________________ Therefore, the present age of Mohan = x = 20 years. The present age of Mohan's mother = y = 4x = 4 × 20 = 80 years.

41. The present age of Mohan's mother is four times that of Mohan's age. Mohan's age ten years from now will beone third of his mother's present age. What are their present ages?

Answer»

Given :-

The present age of MOHAN's mother is FOUR times that of Mohan's age.
Mohan's age ten years from now will be one THIRD of his mother's present age.

To Find :-

The present ages of Mohan and his mother.

Solution :-

Let the present age of Mohan be x and the present age of Mohan's mother be y.

According to the question,

CASE - 1

$\sf{y=<klux>4X</klux>}$ . . .(i)

____________________

CASE - 2

$\sf{x+10=\dfrac{1}{3}\times (y+10) }$

Substituting value of y from (i) :-

$\longmapsto \sf{x+10=\dfrac{1}{3}\times (4x+10) }$

$\longmapsto \sf{3(x+10)=4x+10}$

$\longmapsto \sf{3x+30=4x+10}$

$\longmapsto \sf{30-10=4x-3x}$

$\longmapsto \sf{20=x}$

____________________

Therefore, the present age of Mohan = x = 20 years.

The present age of Mohan's mother = y = 4x = 4 × 20 = 80 years.

Answer»

ANSWER:

Step-by-step explanation:

The figure of the given condition is attached along with the answer.

We are provided with TWO towers 70 m apart. The angle of depression of the top of the smaller tower from the top of the taller tower is 30°. The height of the taller tower is 120 m. We are asked to find the height of the smaller tower.

In the figure, let AB represent the shorter tower and CD represent the taller tower which is 120 m high. BD is the distance between the foot of the two towers, i.e. 70 m.

:

Lets start with solving the problem with given data now!

In Δ ACP,

TAN 30° = CP / AD

1 / √3 = CP / 70

CP√3 = 70

CP = (70 / √3) m

As visible in the figure, AD || BD.

Thus, X = CD - CP

x = 120 - 70/√3

x = (120√3 - 70) / √3

:

x = 79.58 (When you take √3 = 1.73)

16.	The profit obtained when 135 chairs are sold is equal to the cost price of 60 chairs. what is the percentage profit obtained when 26 chairs are given free with the sale of 143 chairs?
Answer» Given :- The profit obtained when 135 CHAIRS are sold is equal to the cost price of 60 chairs. To Find :- what is the PERCENTAGE profit obtained when 26 chairs are given free with the sale of 143 chairs ? Solution :- → Profit = SP - CP → Profit = SP of 135 Chairs - CP of 135 chairs { Given that, Profit is Equal to CP of 60 chairs .} So, → 60 chairs CP = SP of 135 Chairs - CP of 135 chairs → 60 chairs CP + 135 chairs CP = 135 chairs SP → 195 chairs CP = 135 chairs SP → CP / SP = (135/195) → CP / SP = (9/13) → SP / CP = (13/9) → SP = (13/9)CP --------- Eqn.(1) now, given that, → 26 chairs = Given free with the sale of 143 chairs . we can SAY that, when someone buy 143 chairs he gets 26 chairs free . So, → Total chairs he gets = 143 + 26 = 169 chairs = 169CP . Then, → SP of 143 chair = 143SP putting value of Eqn.(1) , → SP of 143 chair = 143 * {(13/9)CP} = (1859/9)CP . Therefore, → Profit Earned = SP - CP = (1859/9)CP - 169CP = (1859 - 1699)CP / 9 = (1859 - 1521)CP/9 = (338/9)CP . Hence, → Profit % = (Profit 100) / (Total CP of all chairs he gets.) → Profit % = [(338/9)CP * 100) / (169CP) → Profit % = (338 * 100) / (1699) → Profit % = 22.22% (Ans*.)

The profit obtained when 135 chairs are sold is equal to the cost price of 60 chairs. what is the percentage profit obtained when 26 chairs are given free with the sale of 143 chairs?

Answer»

Given :- The profit obtained when 135 CHAIRS are sold is equal to the cost price of 60 chairs.

To Find :- what is the PERCENTAGE profit obtained when 26 chairs are given free with the sale of 143 chairs ?

Solution :-

→ Profit = SP - CP

→ Profit = SP of 135 Chairs - CP of 135 chairs

{ Given that, Profit is Equal to CP of 60 chairs .}

So,

→ 60 chairs CP = SP of 135 Chairs - CP of 135 chairs

→ 60 chairs CP + 135 chairs CP = 135 chairs SP

→ 195 chairs CP = 135 chairs SP

→ CP / SP = (135/195)

→ CP / SP = (9/13)

→ SP / CP = (13/9)

→ SP = (13/9)CP --------- Eqn.(1)

now, given that,

→ 26 chairs = Given free with the sale of 143 chairs .

we can SAY that, when someone buy 143 chairs he gets 26 chairs free .

So,

→ Total chairs he gets = 143 + 26 = 169 chairs = 169CP .

Then,

→ SP of 143 chair = 143SP

putting value of Eqn.(1) ,

→ SP of 143 chair = 143 * {(13/9)CP} = (1859/9)CP .

Therefore,

→ Profit Earned = SP - CP = (1859/9)CP - 169CP = (1859 - 169*9)CP / 9 = (1859 - 1521)CP/9 = (338/9)CP .

Hence,

→ Profit % = (Profit * 100) / (Total CP of all chairs he gets.)

→ Profit % = [(338/9)CP * 100) / (169CP)

→ Profit % = (338 * 100) / (169*9)

→ Profit % = 22.22% (Ans.)

Solve Don't tell me if you can't answer it and don't spamThank you.

Answer»

Answer:

$\sqrt{x + 3} = x + <klux>1</klux>$

by squaring on both sides,

${ (\sqrt{x + 3} )}^{<klux>2</klux>} = (x + 1) ^{2} \\ x + 3 = {x}^{2} + {1}^{2} + 2(x)(1)$

$[{a}^{2} + {b}^{2} + 2ab = (a + b) ^{2}]$

$x + 3 = {x}^{2} + 1 + 2x \\ {x}^{2} + 2x + 1 = x + 3 \\ {x}^{2} + 2x - x + 1 - 3 = 0 \\ {x}^{2} + 2x - x - 2 = 0$

Here we didn't subtract 2x-x because if we do factorization again we will GET the same EQUATION.

$x(x + 2) - 1(x + 2) = 0 \\ (x - 1)(x + 2) = 0 \\ here \: (x - 1) = 0 \: (or) \: (x + 2) = 0 \\ x - 1 = 0 \: (or) \: x + 2 = 0 \\ x = 1 \: (or) \: x = ( - 2)$

The value of x is 1 or (-2).

I hope it is HELPFUL.

Be happy

A) A 56.8 kg concrete slab can be balanced by two concrete pillars, each weighing41.3 kg. How many concrete pillars are needed to support slabs that weigh 681.6kg? Calculate the total weight of the slabs and the pillars.

Answer»

Given :- A 56.8 kg concrete slab can be balanced by two concrete pillars, each WEIGHING 41.3 kg. How many concrete pillars are needed to support slabs that weigh 681.6 kg ? Calculate the total weight of the slabs and the pillars. ?

Solution :-

we have given that, A 56.8 kg concrete slab can be balanced by two concrete pillars.

we can say that,

→ 56.8 kg concrete slab can be balanced by = 2 pillar.

So,

→ 1 kg concrete slab can be balanced by = (2/56.8) Pillars.

Than,

→ 681.6kg concrete slab can be balanced by = (2 * 681.6) / (56.8) = 24 Pillar. (Ans.)

Now, we have given that,

→ weight of 1 Pi|lar = 41.3 kg.

So,

→ weight of 24 Pillars = 41.3 * 24 = 991.2 kg.

Therefore,

→ Total weight of slab and the pillars = 681.6 + 991.2 = 1672.8 kg .(Ans.)

A body start with velocity 20m/s after 2 seconds it comes to rest. find the acceleration aquired by the body.

Answer»

__________________________

★ Gɪᴠᴇɴ :-

Initial velocity = 20 m/s
Comes rest after 2 seconds

__________________________

★ Tᴏ Fɪɴᴅ :-

Acceleration ACQUIRED

__________________________

★ Sᴏʟᴜᴛɪᴏɴ :-

Finding acceleration acquired using first equation of motion.

v = u + at

Where,

v → final Velocity = 0 m/s
a → acceleration = ?
u → initial velocity = 20 m/s
t → time TAKEN = 2 s

Note :- Here , the final velocity ( v ) will be zero because the boday comes rest after two second . So , final velocity ( v ) = 0 m/s.

Substituting the values we have,

⇒ 0 = 20 + a(2)

⇒ - 20 = 2a

⇒ a = -20 ÷ 2

⇒ a = - 10 m/s²

Note :- Negative SYMBOL show that the BODY has retardation.

Hence , acceleration of the body is - 10 m/s²

Required raSOLVED EXAMPLESExample 1. Find the co-ordinates of the point P which divides the line segment joiningA(8,9) and B(-7, 4), internally in the ratio 2 : 3.Clearly, y =The co-ord

Answer»

We're GIVEN,

$\longrightarrow \sf{A(8, 9) = ({x}_{1}, {y}_{1})}$

$\longrightarrow \sf{P = (\alpha, \beta)}$

$\longrightarrow \sf{B(-7, 4) = ({x}_{2}, {y}_{2})}$

$\longrightarrow \sf{AP:PB = m:n = 2:3}$

$\sf{\\ \\}$

We know by section formula, when a point $\sf{P(\alpha, \beta)}$ INTERSECTS internally a LINE segment AB where $\sf{A({x}_{1},{y}_{1})}$ and $\sf{B({x}_{2},{y}_{2})}$ in the ratio m : n, then:-

$\quad \quad \longrightarrow \sf{\alpha = \dfrac{m{x}_{2} + n{x}_{1}}{m + n}}$

$\quad \quad \longrightarrow \sf{\beta = \dfrac{m{y}_{2} + n{y}_{1}}{m + n}}$

$\sf{\\ \\}$

So, putting the values,

For alpha,

$\longrightarrow \sf{\alpha = \dfrac{m{x}_{2} + n{x}_{1}}{m + n}}$

$\longrightarrow \sf{\alpha = \dfrac{(2 * -7) + (3 * 8)}{2 + 3}}$

$\longrightarrow \sf{\alpha = \dfrac{ - 14 + 24}{5}}$

$\longrightarrow \sf{\alpha = \dfrac{10}{5}}$

$\longrightarrow \underline{\sf{\alpha = 2}}$

$\sf{\\ \\}$

For beta,

$\longrightarrow \sf{\beta = \dfrac{m{y}_{2} + n{y}_{1}}{m + n}}$

$\longrightarrow \sf{\beta = \dfrac{(2 * 4) + (3 * 9)}{2 + 3}}$

$\longrightarrow \sf{\beta = \dfrac{ 8 + 27}{5}}$

$\longrightarrow \sf{\beta = \dfrac{35}{5}}$

$\longrightarrow \underline{\sf{\beta = 7}}$

$\sf{\\ \\}$

Hence the ANSWER is,

$\longrightarrow{\underline{\underline{\sf{ P = (2,7)}}}}$
