Question

Find interest and amount on rs.750 in 3yrs 4months at 10% per annum

Answer 1

Interest = 250

Amount = 1000

Explanation:

Amount = 750 , Rate = 10% and Time = 3years 4 months.

`time \: = 3 \: years \: 4 \: months \\ = 3 \: years\: + \: (4)/(12) \: months \: = \: 3 \: + (1)/(3) = (1)/(10) years \:`

Rate = 10%

`intrest = (p * r * t)/(100) = (750 * 10 * 10)/(100 * 3) = (750)/(3) = 250 \\`

Amount= Principal + Intrest

= 750 + 250 = 1000

Interest = 250

Amount = 1000
