CAT 2023 Slot 1 Solved Paper

Given, the salaries of Sita, Gita and Mita are initially in the ratio $5:6:7$, respectively, Let us assume their salaries are $5\mathit{p},6\mathit{p}$ and $7\mathit{p}$.
They get salary hikes of $20\%,25\%$ and $20\%$, respectively.
⇒ Their salaries are $6∕5$ * $5\mathit{p},5∕4*6\mathit{p}$ and $6∕5*7\mathit{p}\Rightarrow 6\mathit{p},7.5\mathit{p},8.4\mathit{p}$
Now, Sita and Mita get salary hikes of $40\%$ and $25\%$, respectively
$\Rightarrow$ Sita's salary $=1.4*6\mathit{p}=8.4\mathit{p}$ and Mita's salary $=1.25*8.4\mathit{p}=10.5\mathit{p}$
Let Gita's salary be ' $\mathit{g}$ ' after hike
$\Rightarrow 3\mathit{g}=8.4\mathit{p}+\mathit{g}+10.5\mathit{p}\Rightarrow 2\mathit{g}=18.9\mathit{p}\Rightarrow \mathit{g}=9.45\mathit{p}$
⇒ Hike $\%=\frac{\left(9.45-7.5\right)}{7.5}\times 100=26\%$
