Question

The salaries of $A,$ $B$ and $C$ are in the ratio $2:3:4.$ If the salaries are increased by $10\%,$ $20\%$ and $30\%$ respectively, then the increased salaries will be in the ratio

• A. $11:26:19$
• B. $11:18:25$
• C. $11:18:26$
• D. $11:26:18$

Answer 1

The correct option is C $11:18:26$

Let salaries of $A,$ $B$ and $C$ be $2x,$ $3x$ and $4x$ respectively.

Now, $A^{\prime }s$ salary increases by $10\%$
$\therefore A^{\prime }s$ new salary $=(2x+10\%$ of $2x)=2.2x$
$B^{\prime }s$ salary increases by $20\%$
$\therefore B^{\prime }s$ new salary $=(3x+20\%$ of $3x)=3.6x$
$C^{\prime }s$ salary increases by $30\%$
$\therefore C^{\prime }s$ new salary $=(4x+30\%$ of $4x)=5.2x$
Then, ratio of increased salary
$=2.2x:3.6x:5.2x$
$=11:18:26$
