Question

On the certain sum the interest paid after 3 years is rs. 750 at 5% rate of interest per annum . Find tge sum.​

Answer 1

Answer:

Interest=450

Rate=5%

Time=3years

Principle=?

Principle=(Interest×100)/(Rate×Time)

=(450×100)/(5×3)

=1545000

=3000

therefore

sum paid after 3 years=3000+450=3450

Step-by-step explanation:

Compound interest for 2 years = Rs. 786

Simple interest for 2 years = Rs. 750

Interest for 2 years = I = nCI−SI×100=360786−750×100

=3636×10=10%

P for first year Rs. 3600. Let the time and rate = x

I=PRT⇒1296=3600×x×x⇒x2=0.36∴x=0.6
