There are three baskets filled with some balls. The ratio of the capacity of the first basket to the second basket is 2 : 3 while the ratio of capacity of the second basket to the third basket is 4 : 5. The difference of balls between the first basket and the third basket is 483. What is the number of average balls in all three baskets?

There are three baskets filled with some balls. The ratio of the capacity of the first basket to the second basket is 2 : 3 while the ratio of capacity of the second basket to the third basket is 4 : 5. The difference of balls between the first basket and the third basket is 483. What is the number of average balls in all three baskets? Correct Answer 805

Ratio of capacity of the first basket to second = 2 : 3      ----(1)

Ratio of capacity of the second to third basket = 4 : 5     ----(2)

Multiply by 4 in equation (1) and multiply by 3 in equation (2)

The ratio capacity of the first, second and third basket = 8 : 12 : 15

According to the question

(15 – 8) unit = 483

⇒ 7 unit = 483

⇒ 1 unit = 69

Total number of balls of all three basket = (8 + 12 + 15) × 69 = 35 × 69 = 2415

∴ Required average = 2415/3 = 805
