Question

9. in what time will the Simple Interest on 7 400 at 10% per annum be the same as the
Simple Interest on 1,000 for four years at 4% per annum?​

Answer 1

Answer:

Here , P= Rs 1000

T= 4 yrs

R= 4 %

where, P= Principal

T= Time

R= Rate

Since , Simple Interest on Rs 1000=(1000 × 4 × 4)/100

= Rs 160

now, simple interest=Rs 160

P = Rs 400

R = 10 %

then, T=(100 × SI)/P × R

= (100 × 160)/(400 × 10)

= 4 yr
