Question

A started business with Rs. 4500 and B joined afterwards with Rs. 3000. If the profits at the end of one year were divided in the ratio 2 :1 respectively, then B would have joined A for business after

• A. 1 month
• B. 2 months
• C. 3 months
• D. 4 months

Answer 1

The correct option is C 3 months

Let B entered into the business after x months

$\Rightarrow \frac{4500\left(12\right)}{3000(12-x)}=2/1$

$\Rightarrow 9=12-x$

$\Rightarrow x=3$

B joined business after 3 months
