Question 73

A man buys a watch for Rs. 1950 in cash andsells it for Rs. 2200 at a credit of 1 year. If
the rate of interest is 10% per annum, the man.

Solution

Principal sum = Rs. 1950 and rate of interest = 10%

=> Amount after 1 year = $$1950+\frac{10}{100}\times1950$$

= $$1950+195=Rs.$$ $$2145$$

But, the man sold it for Rs. 2200, => Profit earned = $$2200-2145=Rs.$$ $$55$$

=> Ans - (A)
