Description for Correct answer:
Let initial amount be Rs. x

\( \Large \therefore A => \frac{x}{2} + 40 \)

\( \Large B => \frac{3x}{8} - 120 \)

\( \Large \therefore C's share \)

= \( \Large x - \frac{x}{2} - 40 - \frac{3x}{8} + 120 \)

= \( \Large x- \frac{x}{2} - \frac{3x}{8} + 80 \)

= \( \Large \frac{8x - 4x - 3x}{8} + 80 \)

= \( \Large \frac{x}{8} + 80 \)

According to the question,

\( \Large \frac{x}{8} + 80 = 200 \)

=> \( \Large \frac{x}{8} = 200 - 80 = 120 \)

=> \( \Large x = 120 \times 8 = 960 \)
