Answer 1

Answer:

Step-by-step explanation:

Principal (P) = Rs.10500

Simple Interest (SI) = Rs.1575

Time (T) = 2 years

Let the rate of interest be R.

SI = PRT/100

1575 = 10500 × R × 2 / 100

1575 = 210 × R

R = 1575 ÷ 210

Rate = 7.5%

Answer 2

Answer:

Step-by-step explanation:

Solution,

P=10500

I=1575

T=2years

R=?

Now,

R=I×100÷P×T

R=1575×100÷10500×2

R=157500÷21000

R=7.5 answer
