Question

Balram lent 6,000 to Hemant for 2 years and 1500 to Rakesh for 4 years at the same rute
of interest. Total interest he received from both was 900. Find the rate of interest.
how much time will * 900 become 1.224 at the rate of 12% per annum?​

Answer 1

Answer:

5%

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

S.I. = \frac{Principal\times Time\times Rate}{100}

\therefore \frac{6000\times 2\times R}{100}+\frac{1500\times 4\times R}{100}=900

=>120R+60R=900

=>180R=900

=>R=\frac{900}{180}= 5%

Hence option [A] is the right answer.
