A invested Rs 10,000 for 9 months and B invested Rs 18,000 for some times in a business If the profits of A and B are equal then the period of time for which B’s capital was invested is
A's profit = 10,000 x 9 x r/100
B's profit = 18000 x t x r/100
But the profits are same so,
10,000 x 9 x r/100 = 18000 x t x r/100
so, t = 5 months.
