Question

Krishna deposited Rs 60000 at the rate of 8% in saving account. After 5 years he withdrew Rs long 40000 and total interest of 5 years. How long should he keep the remaining amount to get total interest Rs 28800 from the beginning? Ans: 3 years
​

Answer 1

Answer: 6 Years

Step-by-step explanation:

Money Deposited : Rs.60,000

Interest rate per annum (per year) = 8 %

Interest per annum = ?

=8% of 60000

=8/100 x 60000

=8/1 x 600

= 8 x 600

= Rs.4800 p.a. ( per annum)

Time for interest to add up to Rs.28800 = Rs.28,800/Rs.4,800

= 28000/4800

= 280/48

= 6

Hence, the answer is 6 years. It takes exactly six years for the interest to add up to Rs.28800

I hope this helped!
