Investment:
a = Rs 120,000
b = Rs 135,000
c = Rs 150,000
Ratio of a: b : c = 120,000 : 135, 000 : 150,000
(Divide by 15,000 through)
Ratio of a: b : c = 8 : 9 : 10
Define x:
Let x be the constant ratio:
Ratio of a: b : c = 8x : 9x : 10x
Find a's share:
Total share = 8x + 9x + 10x = 27x
Total share = Rs 56,700
27x = 56,700
x = Rs 2100
8x = 8(2100) = Rs 16800
Answer: Rs 16800
