explaination

let the ratio to be 2x ,5x, 7x

when they all summ they are equal to 280 ( apq)

2x +5x+7x=280

14x=280

x=280/14

x=20

now karan get 2 *x=2*20=40 marbels

    rahim get=5*x=5*20=100 marbels

Answer 2

GIVEN :-

• There are total 280 marbles.
• It is divided among Karan , Rahim and Rohan in the ratio 2:5:7 respectively.

TO FIND :-

• Difference in the number of marbles Karan and Rohan get.

SOLUTION :-

Marbles are divided in a ratio . So , it has a common multiple , let 'x'.

Number of marbles ,

• Karan got → 2x
• Rahim got → 5x
• Rohan got → 7x

Sum of all marbles is 280.

→ 2x + 5x + 7x = 280

→ 14x = 280

→ x = 280/14

→ x = 20

Hence ,

• Karan got → 2x = 2(20) = 40
• Rahim got → 5x = 5(20) = 100
• Rohan got → 7x = 7(20) = 140

Therefore , Karan got 40 marbles , Rahim got 100 marbles and Rohan got 140 marbles.

♦ Difference in marbles of Rohan and Karan,

= 140 - 40

= 100

Hence , difference between the number of marbles Karan and Rohan get is 100.
