Given are as follows :-
Rate = 5%pa
Time = 3months
Amount = 2025
Firstly we change time into years
As we in 12 month = 1 year
3month = 3 / 12 = 1/4 years
interest = Rs 2025 - P
2025 - P = P* 1/4 * 6/ 100
2025 - P = 0.25 *6 / 100
2025 - p = 1.5 / 100
2025 = 1.5/100 +P
2025 = 150 p / 100
cross multiply
150P = 2025 * 100
P = 202500/ 150
P = 1350
