16.	The perimeter of a right triangle is 60 cm. it's hypotenuse is 25 cm. find the area of the triangle.
Answer» Perimeter of that triangle = 60cm the measure of hypotaneous = 25cm then the rest sides must measure = 60-25 = 35 let one side be x then, thw measure of the third side must be 35 - x using pythagoras theorem (25)^2 =(x)^2 + (35-x)^2 625 = x^2 + x^2 - 70x + 1225 x^2 + x^2 - 70x + 1225 = 625 x^2 + x^2 - 70x + 1225 -625 = 0 2 x^2 - 70x + 600 = 0 2x^2 - 40x - 30 x + 600= 0 2x (x-20) -30 ( x - 20) = 0 (x-20)(2x-30)=0 x -20 = 0 x = 20 2x -30 =0 2x =30 x = 15 so, one of the side measure EITHER 20 cm 15 cm if one side measure 20cm then the other must measure 35 -20 = 15cm and if it measured 15 cm then the other side measure 35-15 = 20 cm so, we will get 20cm and 15 cm as our remaining sides. one of then will be height and the other misy be the base, now apply the formula of area of triangle i.e (1/2) (height)(base) = (1/2 )(20)(15) = 150 cm^2 so, the area of that triangle will be 150 cm^2.

16.

The perimeter of a right triangle is 60 cm. it's hypotenuse is 25 cm. find the area of the triangle.

Answer»

Perimeter of that triangle = 60cm

the measure of hypotaneous = 25cm

then the rest sides must measure = 60-25

= 35

let one side be x

then, thw measure of the third side must be 35 - x

using pythagoras theorem

(25)^2 =(x)^2 + (35-x)^2

625 = x^2 + x^2 - 70x + 1225

x^2 + x^2 - 70x + 1225 = 625

x^2 + x^2 - 70x + 1225 -625 = 0

2 x^2 - 70x + 600 = 0

2x^2 - 40x - 30 x + 600= 0

2x (x-20) -30 ( x - 20) = 0

(x-20)(2x-30)=0

x -20 = 0

x = 20

2x -30 =0

2x =30

x = 15

so,

one of the side measure EITHER 20 cm 15 cm

if one side measure 20cm then the other must measure 35 -20 = 15cm

and if it measured 15 cm then the other side measure 35-15 = 20 cm

so,

we will get 20cm and 15 cm as our remaining sides.

one of then will be height and the other misy be the base,

now apply the formula of area of triangle i.e

(1/2) (height)(base)

= (1/2 )(20)(15)

= 150 cm^2

so, the area of that triangle will be 150 cm^2.

Answer» solution Let the speed of the motor boat in STILL water be x km/h. Let the rate of flow of the stream be y km/h Speed of boat upstream = (x - y) km/h.

Motarboat takes 6 hrs. to cover 100km downstream and 30km uostream . if the motorboat goes 75km downstream and returnbacks to it's starting point in 8 hours , find the speed of the motorboat in still water and the rate of stream .

Answer»

solution

Let the speed of the motor boat in STILL water be x km/h.

Let the rate of flow of the stream be y km/h

Speed of boat upstream = (x - y) km/h.

Speed of boat downstream = (x + y)km/h.

we know time = distance/speed.

now , A to Q,

Time for 100 km downstream and 30 km upstream

100/(x + y) + 30/(x - y)

And it takes 6 hrs to cover downstream and upstream. Then

100/(x + y) + 30/(x - y) = 6

Time for 75 km downstream and RETURNING (means 75 km upstream)

= 75/(x + y) + 75/(x - y)

Given that the time taken is 8 hours

75/(x + y) + 75/(x - y) = 8

now the equation should be .

100P + 30q = 6

50p + 15q = 3------------( 1 )

75p + 75q = 8----------( 2 )

from--------( 1 ) &---------( 2 )

multiply by ( 3 ) in -----( 1 )

250p + 75q = 15

75p + 75q = 8

(–)__(–)(–)

-------------------------------

175p = 7

p = 1/25 [ put in -------( 1 ) ]

50(1/25) + 15q = 3

2 + 15q = 3

q = 1/15 = 1/(x - y)

x - y = 15------------( 3 )

p = 1/25 = 1/(x + y)

x + y = 25---------( 4 )

From---------( 3 ) &----------( 4 )

x - y = 15

x + y = 25

---------------

2x = 40

x = 20 [ put in ------( 3 ) ]

x - y = 15

20 - y = 15

y = 20 - 15

y = 5 , x = 20

Hence, the speed of the motor boat in still water is 20 km/h and rate of flow of the stream is 5 km/h.

प्रश्न 33. यदि केले 2 रु. 50 पैसे प्रति दर्जन से खरीद कर 25 पैसे केलेके भाव से बेचे, तो लाभ कितने प्रतिशत होगा?

Answer»

प्रश्न :- यदि केले 2 रु. 50 पैसे प्रति दर्जन से खरीद कर 25 पैसे प्रति केले

के भाव से बेचे, तो लाभ कितने प्रतिशत होगा ?

उतर :-

→ क्रय मूल्य = ₹2.5 प्रति दर्जन

→ विक्रय मूल्य = 25 पैसे प्रति केले

यानि :-

→ 1 केले का विक्रय मूल्य = 25 पैसे

→ 1 दर्जन केले का विक्रय मूल्य = 25 * 12 = 300 पैसे = ₹3

अत :-

→ कुल लाभ = विक्रय मूल्य - क्रय मूल्य

→ कुल लाभ = 3 - 2.5

→ कुल लाभ = ₹0.5

अब :-

→ लाभ % = (लाभ * 100) / क्रय मूल्य

→ लाभ % = (0.5 * 100) / 2.5

→ लाभ % = (50) / 2.5

→ लाभ % = (500/25)

→ लाभ % = 20%

इसलिए इस दशा में 20% का लाभ होगा ll

प्रश्न 29. विकास ने एक घोड़ा 690 रु. में बेच कर 15% का लाभ प्राप्तकिया। घोड़े का क्रय मूल्य ज्ञात कीजिए।

Answer»

प्रश्न :- विकास ने एक घोड़ा 690 रु. में बेच कर 15% का लाभ प्राप्त

किया। घोड़े का क्रय मूल्य ज्ञात कीजिए ?

उतर :-

→ घोड़े का विक्रय मूल्य = 690 रु.

→ लाभ % = 15%

→ घोड़े का क्रय मूल्य = (विक्रय मूल्य * 100) / (100 + लाभ %)

→ घोड़े का क्रय मूल्य = (690 * 100) / (100 + 15)

→ घोड़े का क्रय मूल्य = (690 * 100) / 115

→ घोड़े का क्रय मूल्य = ₹600

अत : घोड़े का क्रय मूल्य ₹600 था ll

The sum of three consecutive odd integers is 255. What are the integers , only frame the equation.

Motarboat takes 6 hrs. to cover 100km downstream and 30km uostream . if the motorboat goes 75km downstream and returnbacks to it's starting point in 8 hours , find the speed of the motorboat in still water and the rate of stream .

solution

Let the speed of the motor boat in STILL water be x km/h.

Let the rate of flow of the stream be y km/h

Speed of boat upstream = (x - y) km/h.

Speed of boat downstream = (x + y)km/h.

we know time = distance/speed.

now , A to Q,

Time for 100 km downstream and 30 km upstream

100/(x + y) + 30/(x - y)

And it takes 6 hrs to cover downstream and upstream. Then

100/(x + y) + 30/(x - y) = 6

Time for 75 km downstream and RETURNING (means 75 km upstream)

= 75/(x + y) + 75/(x - y)

Given that the time taken is 8 hours

75/(x + y) + 75/(x - y) = 8

now the equation should be .

100P + 30q = 6

50p + 15q = 3------------( 1 )

75p + 75q = 8----------( 2 )

from--------( 1 ) &---------( 2 )

multiply by ( 3 ) in -----( 1 )

250p + 75q = 15

75p + 75q = 8

(–)______(–)____(–)

-------------------------------

175p = 7

p = 1/25 [ put in -------( 1 ) ]

50(1/25) + 15q = 3

2 + 15q = 3

q = 1/15 = 1/(x - y)

x - y = 15------------( 3 )

p = 1/25 = 1/(x + y)

x + y = 25---------( 4 )
