Fresh fish=Rs.65 dry fish=Rs.75 King fish=Rs.105 Gracy buys 2kg Fresh fish, 1kg Dry Fish,4kg King fish and pays Rs.1000.What amount will she get back?

Answer»

Step-by-step explanation:

Given Fresh FISH=Rs.65 dry fish=Rs.75 King fish=Rs.105 GRACY buys 2KG Fresh fish, 1kg Dry Fish,4kg King fish and pays Rs.1000.What amount will she get back?

  • Given Fresh fish is Rs 65 for 1 kg
  • Dry fish is Rs 75 for 1 kg
  • King fish is Rs 105 for 1 kg
  • So Gracy will buy 2 kg of Fresh fish = 2 x 65 = Rs 130
  •                                1 kg of Dry fish = 1 x 75 = Rs 75
  •                                4 kg of King fish = 4 x 105 = Rs 420
  • Now total amount she has to pay will be 130 + 75 + 420 = Rs 625
  • Now she has paid Rs 1000.
  • Therefore Amount she has to get back will be 1000 – 625 = Rs 375

A grocer purchased 80 kg of sugar at Rs. 13.50 per kg and mixed it with 120 kg sugar at Rs. 16 per kg. At what rate should he sell the mixture to gain 16% ?

Answer»

Answer:

RS 17.40 Per Kg

Step-by-step EXPLANATION:

C.P of 200 kg of MIXTURE = Rs. (80 X 13.50 + 120 x 16) = Rs. 3000

S.P. = 116% of Rs. 3000 ∴ \ = Rs.    \left({116\over100}× 3000\right) = Rs.3480

∴ Rate of S.P of the mixture  = Rs 3480 / 200 per Kg = Rs 17.40 Per Kg

The scale on a map is 1 : 25 000 How many kilometres on the ground is represented by 9 cm on the map

Answer»

Hyy Dude

If we DIVIDE 4.5 km by 0.5 km we GET 9, so the distance on the map must be 9 cm. working out what 1 cm on the map is equivalent to as a real life distance. A map has a scale of 1:25000. This means that 1 cm on the map is 25000 cm in real life, which is 250 m or 0.25 km.

Express 2.35 with a bar on 35 in p by q

Answer»

Answer:

given :- 2.353535...

let x = 2.353535... …(i)

MULTIPLY both SIDES by 100

100 × x = 100 × 2.353535...

100X = 235.353535... …(ii)

SUBTRACT (i) from (ii)

100x - x = 235.353535... - 2.353535...

99x = 235

x = 235/99

hence, 235/99 is the form of p/q of 2.353535...

let an amount of rs 47000 be divided into three parts such that three times the firat is equal to four times the second and five times the third. find the difference between the largest and the smallest parts .....its important plz answer​

Answer»

Answer:

Let the THREE NUMBERS be = x, y and z

According to the given question :-

x = 3y ...(1)

z = 5x ...(2)

We can also find that :-

3y = \TT{\frac{z}{5}}\\

y = \tt{\frac{z}{15}}\\ ...(3)

Average = 57

=》 \SF{\frac{x+y+z}{3} = 57}\\

Replace the values by (1),(2) and (3)

=》 \sf{\frac{3y+y+15y}{3} = 57}\\

=》 \sf{\frac{19y}{3} = 57}\\

=》 \sf{y = 9}

\sf{x = 3y = 27}

\sf{z = 5x = 135}

Question:

if if X and Y are 2×2 matrices,then SOLVE the following Matrices equation for X and Y ,

2X + 3Y = X=\left[\begin{array}{cc}2&3\\4&0\end{array}\right]

3X+2Y = X=\left[\begin{array}{cc}-2&2\\1&-5\end{array}\right]

THEORY :

A rectangular arrangement of numbers in row and column is called a matrix.

Properties of Matrices:

1) Addition of Matrices

If A,B and C are matrices of same order then ,

  • A+B = B+A
  • (A+B)+C = A+(B+C)
  • A+O = A ,where O is zero matrix

2)Scalar multiplication of Matrix

Let A= (a_{ij})_{m\timesn} and k be a number

kA = Ak = (ka_{ij})_{m\timesn}

Solution :

X=\left[\begin{array}{cc}-2&0\\-1&-3\end{array}\right]

Y=\left[\begin{array}{cc}2&1\\2&2\end{array}\right]

A man had Rs 20878560in his bank.He withdrew Rs 4836980in January,Rs 395648 in the month of February and Rs 45000 in the month of March.What is the amount remaining in his bank account by the end of M

Answer»

ANSWER:

Money he had in the bank = ₹20,878,560

Withdrew in MONTH of January = ₹4,836,980

Withdrew in month of FEBRUARY = ₹395,648

Withdrew in month of MARCH = ₹45,000

Therefore, REMAINING balance in the month of May =

20,878,560 - ( 4,836,980 + 395,648 + 45,000)

= 15,600,932

Write the four largest 2-digit multiple of 6.

Answer»

Step-by-step explanation:

you take the LARGEST 2 digit number which is 99 and divide it by 6.

on doing so u get 16 as the QUOTIENT and 3 as the remainder.

Now the largest 2 digit multiple of 6 is 99-3 = 96

the other 3 multiples are:

6 * 15 = 90

6 * 14 = 84

6 * 13 = 78

Equation of tangent on the curve Y=e-|x| at the point where it cuts the line x=1

Answer»

Question :

Equation of TANGENT on the curve y = e {}^{ -  |<klux>X</klux>| } at the point where it cuts the line x=1

Theory ;

Equation of tangent to a given curve :

LET y= f(x) be a curve and let p(x_{1},y_{1}) on it .Then ,

\dfrac{dy}{dx}  = m =  \bf slope \: of  \: tagent \: at  \:  p

⇒The equation of tangent at p(x_{1},y_{1}) to the curve y=f(x) is

\bf (y  - y_{1}) =  \frac{dy}{dx} (x - x_{1})

Solution :

Given :

y = e {}^{ -  |x| }

To find :

we have to find equation of tangent at the point where it cuts the line x=1

_______________________________

y = e {}^{ -  |x| }

Here x= 1 i.e |x| = x [ x >0]

\implies y = e {}^{ - x}

Now Differentiate with respect to x

\dfrac{dy}{dx}  = e {}^{ - x} \times  - 1

\bf  \dfrac{dy}{dx} (at  \: x = 1)= \bf  \dfrac{ - 1}{e}   = m

Now put the value of x = 1 in the curve equation

y = e {}^{ - 1}  =  \frac{1}{e}

⇒Point (1,\dfrac{1}{e})

Equation of the tangent (1,\dfrac{1}{e}) is

(y -  \frac{1}{e} ) =  \frac{1}{e}(x - 1)

\implies \frac{ey - 1}{e} =  \frac{ - 1}{e} (x - 1)

\implies \bf x   + ey - 2 = 0

_______________________________

THEREFORE, the Equation of tangent on the curve y = e {}^{ -  |x| } at the point where it cuts the line x=1 is :

{\purple{\boxed{\large{\bold{x+ey-2=0}}}}}
