Question

Rama invests an amount of Rs.24,200 at the rate of 4 p.c.p.a. for 6 years to obtain
a simple interest. Later he invests the principal amount as well as the amount ob-
tained as simple interest for another 4 years at the same rate of interest. What
'amount of simple interest will he obtain at the end of the last 4 years?
1) Rs. 4,800 2) Rs. 4,850.32 3) Rs.4801.28 4) Rs. 4,700​

Answer 1

In the case I,

SI=P×R×T100=24200×4×6/100

,

=RS.5808

.

Amount = Principal + SI

,

SI = 24200 + 5808 = 30008

,

In the case II,

SI=30008×4×4/100 = RS.4801.28.

So,the answer obtained is RS.4801.28.

Hope it helps you,
