7.

a rectangular Park 54 metre into 40 metre has 2 metre wide roads in the centre running parallel to the breadth find the area of the roads area of the park excluding roads cost of laying grass at rupees 5 per square metre

Answer»

ANSWER:

area of PARK = 54×40= 2160 m²

BREADTH of road = 2m

breadth of Park = length of road

length of road = 40 m

Area of road = 2×40 = 80m²

REMAINING area = 2160-80 = 2080m²

23.	A, B को 20% के लाभ पर एक वस्तु बेचता है \| B वही वस्तु C को 15% के लाभ पर बेच देता है \| C ने A को वस्तु के क्रय मूल्य से रू. 190 अधिक का भुगतान किया \| A को कितना लाभ प्राप्त हुआ?
Answer» Answer: 100 Step-by-step explanation: Let the cost PRICE of article is = x A SELLS article to B at the profit of 20% = 120% of x Now, B sells article to C at the profit of 15% = 120% × 115% of x = 138% of x According to the question, difference between C and A = 190₹ 38% = 190 1 % = 5 100% = 500 hence, cost price is 500 Therefore A's profit is = 500×120/100 = 5×120 = 600 Thus the profit of A is = 600 - 500 = 100

23.

A, B को 20% के लाभ पर एक वस्तु बेचता है | B वही वस्तु C को 15% के लाभ पर बेच देता है | C ने A को वस्तु के क्रय मूल्य से रू. 190 अधिक का भुगतान किया | A को कितना लाभ प्राप्त हुआ?

Answer»

Answer:

100

Step-by-step explanation:

Let the cost PRICE of article is = x

A SELLS article to B at the profit of 20%

= 120% of x

Now, B sells article to C at the profit of 15%

= 120% × 115% of x

= 138% of x

According to the question,

difference between C and A = 190₹

38% = 190

1 % = 5

100% = 500

hence, cost price is 500

Therefore A's profit is = 500×120/100

= 5×120 = 600

Thus the profit of A is = 600 - 500 = 100

Answer» Let the unit DIGIT be y & tens digit be x. Original number = (10x+y) After interchanging the digits NEW number = (10y+x) (10x+y) + (10y+x) = 110 11x +11y = 110 11(x+y)= 110 x+y = 110/11 x+y= 10…………...(1) x= 10-y……………(2) (10x+y) - 10 = 4+ 5(x+y) (10x+y) - 10 = 4+ 5(10) (10x+y) = 4+ 50+10 (10x+y) = 64 10(10-y) +y = 64 100-10y +y= 64 100 -9y = 64 -9y = 64-100 -9y = -36 y= 36/9= 4 y= 4 putting the value of y in EQN 2 x= 10-y x= 10-4 x= 6 Hence , the first number is 6 & second number is 4. Original Number is 10x+y = 10× 6+4= 60+4= 64

38.

the sum of two digit number and the number formed by interchanging its digits it 110 if 10 is subtracted from the first number the new number is four more than the five times of the sum of the digits in the first number find the first number

Answer»

Let the unit DIGIT be y & tens digit be x.

Original number = (10x+y)

After interchanging the digits

NEW number = (10y+x)

(10x+y) + (10y+x) = 110

11x +11y = 110

11(x+y)= 110

x+y = 110/11

x+y= 10…………...(1)

x= 10-y……………(2)

(10x+y) - 10 = 4+ 5(x+y)

(10x+y) - 10 = 4+ 5(10)

(10x+y) = 4+ 50+10

(10x+y) = 64

10(10-y) +y = 64

100-10y +y= 64

100 -9y = 64

-9y = 64-100

-9y = -36

y= 36/9= 4

y= 4

putting the value of y in EQN 2

x= 10-y

x= 10-4

x= 6

Hence , the first number is 6 & second number is 4.

Original Number is 10x+y = 10× 6+4= 60+4= 64
