(1) A’s investment = Rs. x
∴ B’s investment = Rs.(x + 600)
C’s investment = Rs.(2x + 600)
∴ x + x + 600 + 2x + 600 = 15600
⇒ 4x = 15600 – 1200 = 14400
⇒ x =

14400

4

= 3600
∴ B’s investment =Rs. 4200
C’s investment
= Rs.(2 × 3600 + 600)
= Rs.7800
∴ A : B : C = 3600 : 4200 : 7800
= 6 : 7 : 13
Sum of the terms of ratio
= 6 + 7 + 13 = 26
∴ A’s share
= Rs.(

6

26

×10400 )
= Rs.2400
