Question

A began a business with Rs. 85,000. He was joined afterwards by B with Rs. 42,500. For how long is B in the business, if the profits at the end of the year are divided in the ratio of 3 : 1?

• A. 4 months
• B. 5 months
• C. 6 months
• D. 7 months
• E. 8 months

Answer 1

The correct option is E

8 months

Suppose B joined for x months.

Then, $(\frac{85000\times 12}{42500\times x}=\frac{3}{1})$

$\Rightarrow x=\left(\frac{85000\times 12}{42500\times 3}\right)=8$

So, B joined for 8 months.
