Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 1,562.

Given, A : B = 3 : 4

Also, B : C = 5 : 9 

Now, A : B : C = 15 : 20 : 36

Let the shares of A, B and C be 15x, 20x and 36x respectively.

36x - 15x = 462

⇒ 21x = 462

⇒ x = 22

Total sum = 15x + 20x + 36x

⇒ 71x = 1562
