A began a business with ₹ 85000. He was joined afterwards by B with ₹ 42500. For how much period does B join, 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)8 months
Answer
Answer (as printed): D
Explanation
Suppose B joined for $x$ months. Then, $\frac{85000 \times 12}{42500 \times x}=\frac{3}{1}$ or $x=\frac{85000 \times 12}{42500 \times 3}=8$. So, B joined for 8 months.
