A invests 10,000 rupees in his business, 7 months later, B invests 12,000 rupees. After 1 year, the profit is 30,000 rupees. What's B's share?



I am having troubles constructing the formula for B's share. Please help.

  • There is not enough information. Maybe all the profit was generated over the first seven months, in which case $B$ gets no share of the profit. Maybe a much bigger profit was realized over the first seven months with significant losses thereafter. In that case, $B$ would have a loss.

  • Let's assume the profit happened on the 12th month's end?

  • Please edit your post to include all your assumptions. That said, under that assumption (unless they had agreed differently) they should share pro rata, so $B$ would get $frac 1200012000+10000=frac 611$ of the profit.

  • More broadly, the natural answer would be that $B$ should get $frac 1200012000+A(7)$ of the profit where $A(7)$ is the value of $A's$ investment at the time of $B's$ investment. Of course, all that should be agreed in advance by $A,B$.

Let us take the ratio in which they should share the profit



$=$ Ratio of the investments multiplied by the time period.
$$=10000times12:12000times5\=120:60\=2:1\=A:B$$
So, their share is in ratio of $2:1$



They had a total profit of $30000$ in which $A$ receives $20000$ and $B$ receives $10000$
