Question

The monthly salary of A , B , C is in the proportion of $2:3:5$.If C's monthly salary is Rs.1200 more than that of A , then B's annual salary is

• A. Rs.$14400$
• B. Rs.$24000$
• C. Rs.$1200$
• D. Rs.$2000$

Answer 1

The correct option is A Rs.$14400$

$\Rightarrow$ Let the monthly salary of A, B, C be $Rs.2x,Rs.3x$ and $Rs.5x$ respectively.

$\Rightarrow$ Then, $5x-2x=1200$

$\Rightarrow$ $3x=1200$

$\therefore$ $x=400$

$\Rightarrow$ $B^{\prime }s$ monthly salary = $3x=3\times 400=Rs.1200$

$\Rightarrow$ Hence, $B^{\prime }s$ annual salary = $Rs.(12\times 1200)=Rs.14400$
