1. A, B, C started a business with their investments in the ratio 1 : 3 : 5. After 4 months, A invested the same amount as before and B as well as C withdrew half of their investments. The ratio of their profits at the end of the year is ?

A. 4 : 3 : 5

B. 5 : 6 : 10

C. 6 : 5 : 10

D. 10 : 5 : 6

Solution:

Let their initial investments be x, 3x and 5x respectively
Then,

= A : B : C

= (x \times 4 + 2 x \times 8)

(3 x \times 4 + \frac{3 x}{2} \times 8)

(5 x \times 4 + \frac{5 x}{2} \times 8)

\begin{aligned} = 20 x : 24 x : 40 x \\ = 5 : 6 : 10 \end{aligned}
