Partnership Practice Test 1

$\begin{array}{ccc}\mathit{A}& \mathit{B}& \mathit{C}\\ \frac{9}{10}& \frac{1}{20}& \frac{1}{20}\end{array}$
Let the total investment = x
Profit per cent = 12%
Profit $=\frac{12}{100}\mathit{x}$
New profit $=\frac{15}{100}\mathit{x}$
A’s increased income = Rs 270
According to the statement,
$\frac{9}{10}\left(\frac{15}{100}\mathit{x}\right)-\frac{9}{10}\left(\frac{12}{100}\mathit{x}\right)=270$
$\frac{9}{10}\left(\frac{3}{100}\mathit{x}\right)=270$
$\mathit{x}=10,000$
Share of B = $\frac{1}{20}\left(10,000\right)$ = Rs 500
Share of C = $\frac{1}{20}\times 10,000$ = Rs 500
