Question

Three boys sell some magazines for a total
profit of 400. The profit is shared between
them in a ratio equal to the number of
magzines they sell. If they sell 70, 80 and 100
magzines, how much profit does each receive ?​

Answer 1

the no. of magazines they sell are 70 , 80,100

so, the profit earned by them will be,

70x , 80x and 100 x respectively.

the total profit earned is equal to 400

hence,

70x + 80x + 100x = 400

250 x = 400

x = 40/25

x = 8/5

so, profit received by each will be,

$70x = 70 \times \frac{8}{5} = 112 \\ \\ 80x = 80 \times \frac{8}{5} = 128 \\ \\ and \\ \\ 100x = 100 \times \frac{8}{5} = 160$

HENCE PROFIT RECEIVED BY BOY SELLING 70,80 AND 100 WILL BE 112, 128 AND 160 RESPECTIVELY .

Answer 2

Given :

Three boys sell some magazines for a total profit of Rs. 400. The profit is shared between them in a ratio equal to the number of magazines they sell. If they sell 70, 80 and 100 magazines.

ㅤㅤㅤㅤ

To find :

How much profit does each receive?

ㅤㅤ

Calculations :

• Sum of magazines = 70 + 80 + 100

• Sum of magazines = 250

ㅤㅤ

For first boy:

= 400 × 70/250

= 28000/250

= ₹112

ㅤㅤ

For second boy:

= 400 × 80/250

= 32000/250

= ₹128
