Question

3. Find the rate of interest (R)

(a) Principal = Rs. 1460 Time (T)= 30 months
Interest = Rs. 292​

Answer 1

8 percent

Explanation:

p=rs1460

t=30month

=30÷12(1year=12months)

=2.5 years

interest=rs292

rate of interest=?

we know that

I=ptr/100

rs292=rs1460×2.5×R/100

rs2920=365R(subtracting 0 from both and multiplying remaining with 292)

2920/365=r

8 percent=R
