Question

Find the time when simple interest on ₹3.3 lakhs at 6.5% per annum is ₹75075

Answer 1

P=Rs 330000
SI=Rs 75075
r=6.5%
t=?
SI=P*r*t/100
t=SI*100/P*r
=75075*100/330000*6.5
=7/2 yrs
=3 1/2 yrs

Answer 2

Here,

P = 3.3 lakhs

= Rs 3.3 × 100000

= Rs 330000

R = 6.5% per annum

I = Rs 75075

Hence,

T = (I × 100) / (P × R)

= (75075 × 100) / (330000 × 6.5) years

= (75075 × 100 × 10) / (330000 × 65) years

On further calculation, we get,

= (75075) / (330 × 65) years

= 1155 / 330 years

We get,

= 7 / 2 years
