A person buys a house for 15 lacs and sells it for 20 lacs. After five years he buys the same house at 30 lacs and sells it for 40 lacs. What is the overall profit percent for that person over both the transactions?

  • A.30.33%
  • B.33.33%
  • C.35.33%
  • D.40.33%

Answer: B

The overall profit is 33.33%.

Treat the two deals as one: add up everything paid and everything received.

\[ \begin{aligned} \text{cost} &= 15 + 30 = 45\ \text{lacs} \\ \text{sale} &= 20 + 40 = 60\ \text{lacs} \\ \text{profit} &= \frac{15}{45} \times 100 = 33.33\% \end{aligned} \]

Each deal on its own also gives a third: a profit of 5 on 15 and of 10 on 30, both 33.33%, which confirms the result. The other options differ only in the whole number and do not come from this calculation.
