A, B, and C subscribe to a sum of Rs75,500 for a business. A subscribes Rs.3,500 more than B, and B subscribes Rs 4, 500 more than C. Out of a total profit of Rs 45, 300, how much ( in Rs) does A receive?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 17,400.

We know that,

Person's Profit = Investment × time

Now,

Let x be the investment of C

⇒C = x

B subscribes Rs 4, 500 more than C

⇒B = (x + 4500)

A subscribes Rs.3,500 more than B

⇒A = (x + 4500 + 3500)

We know that,

⇒ x + (x + 4500) + (x + 4500 + 3500) = 75500

⇒ x + (x + 4500) + (x + 8000) = 75500

⇒ 3x + 12500 = 75500

⇒ 3x = 63000

⇒ x = 21000

Put the value of x 

We get,

⇒A = x + 4500 + 3500 = 21000 + 4500 + 3500 = 29000

⇒B = x + 4500 = 21000 + 4500 = 25500 and,

⇒C = x = 21000

⇒Ratio of profit = A : B : C = 29000 : 25500 : 21000 = 58 : 51 : 42

Thus,

A's share = 58/(58 + 51 + 42) × 45300

⇒ 58/151 × 45300 = Rs.17400
