Question

Three sisters A, B, C whose ages are in the ratio 7 : 4 : 3, had to divide the total of 770 pearls among them in the ratio of their ages. How many pearls did C get?

Answer 1

Answer:

165 pearls will be provided to C

Explanation:

Let their ages be 'x';

A=7x,B=4x,C=3x;

7x+4x+3x=770;

14x=770;

x=55;

so the value of x is 55;

C=3x;

C=3×55;

C=165;

Answer 2

Answer:

165

Explanation:

We are given that threes sisters A,B and C whose ages are in the ration 7:4:3.

Total number of pearls=770

We have to find that how many pearls C get

Sum of ration=7+4+3=14

Number of pearls C get =$\frac{corresponding\;number\;of\;C\;in\;the\;ratio}{sum\;of\;ratio}\times total\;pearls$

Substitute the values then , we get

Number of pearls C get=$\frac{3}{14}\times 770=3\times 55=165$

Hence, C get pearls=165
