Question

what sum of money lent out at 6%p.a for 2years will give the same interest as rupees 1,800lent out at 5%p.a for a year​

Answer 1

Answer:

First, there is a need to take out the Simple interest.

Given,

Principal (P) =Rs. 1800

Rate (R) = 5 %

Time (T) = 1 year

Method,

S.I. = p*r*t/100

Solution,

x = 1800*5*1/100

After Cancellation,

Rupees 90

2nd case,

Simple Interest = Rs. 90 (As solved above)

Rate = 6 %

Time = 2 years

Method,

P = s.i*100/r*t

Solving,

x = 90*100/6*2

After cancellation...

Rupees 750

Hence, the principal should be Rs. 750
