In a business, A and B gained some amount in a certain ratio, and B and C received the profit in the ratio as that of A and B. If A received 6400 and C received 10000. Find the share of B.

Answer & explanation

Correct answer: option 3

Let A : B = x : y

then, B : C = x : y .....ATQ

Now, A : B : c = x² : xy : y²

ATQ,

⇒ x² = 6400 ⇒ x = 80, and

⇒ y²= 10000 ⇒ y = 100

Therefore, B's share = xy = 80 × 100 = 8000
