Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e  9024.

It is given that,

A : B  = 9 : 8 and A : C = 4 : 5.

In both, the ratio A is common so the value of A must be equal.

to make A equal in both the ratio one must multiply the first ratio by 4 and the second ratio by 9,

Now A : B  = 36 : 32 and A : C = 36 : 45

So A : B : C = 36 : 32 : 45.

Share of B = 32113\frac{32}{113} × 31866 = ₹9024.
