A bank gives simple interest at the rate of 4.5% per annum. How much money (in ₹) should a person deposit to get ₹7,500 as interest every year?
- A1,33,333.33
- B2,33,333.33
- C2,66,666.67
- D1,66,666.67
Solution & Step-by-step Explanation
The formula for Simple Interest (SI) is:
SI=
100
P×R×T
Given:
SI=₹7,500
R=4.5% per annum
T=1 year
Substitute the values into the formula to find the principal P:
7500=
100
P×4.5×1
7500×100=4.5P
750000=4.5P
P=
4.5
750000
=
45
7500000
P=
3
5000000
≈1,66,666.67
