Question

A began a business with rs 85,000. He was joined afterwards by b with 42,500. If the profits at the end of the year are divided in the ratio of 3:1, then after how much period did b join a?

Answer 1

profit=principle*time

85000*12/42500*x=3/1

x=8

Answer 2

B joined for 8 months

Solution:

Let B join after "x" months

A began a business with rs 85,000

He was joined afterwards by b with 42,500

Profit ratio = 3 : 1

Then we can say,

$\frac{85000 \times 12 }{42500 \times x} =\frac{3}{1}\\\\x = \frac{85000 \times 12 }{42500 \times 3 }\\\\x = 8$

Thus B joined for 8 months
