Question
A total of Rs.71,000 was distributed among three
individuals named Ashish, Bheem, and Chinu. The amount Ashish received compared to Bheem was in the ratio of 5:8, and the amount Bheem received compared to Chinu was in the ratio of 3:4. Determine the difference in the amounts received by Ashish and Chinu.Solution
ATQ, Let, the share of 'Bheem' be Rs. '24a'. So, the share of 'Ashish' = (5/8) × 24a = Rs. '15a' Share of 'Chinu' = (4/3) × 24a = Rs. '32a' ATQ, 15a + 24a + 32a = 71000 Or, 71a = 71000 So, a = (71000/71) = 1000 Therefore, required difference = 32a - 15a = 17a = Rs.17,000
