Question

A lent Rs.1500 to B for 3 years and Rs.2000 to C for 2 years at a certain rate of interest and receive Rs.340 as total interest. Find the rate of interest.​

Answer 1

Answer:

4%

Step-by-step explanation:

rate of interest be R% p.a. then,

S.I. = {Principal*times *Rate}/{100}

therefore

{1500*3*R}/{100}+{2000*2* R}/{100}=340

=>45R+40R=340

=>85R=340

=>R=\{340/85}= 4%
