SI= SIMPLE INTEREST, P= PRINCIPAL, N= TIME, R= RATE OF INTEREST AND I= INTEREST



1. We know that SI= P×N×R / 100
Therefore, to find principal
P= I×100/N×R
=600×100/3×4
=60000/12
=5000 rupees

2. We kbow that SI= P×N×R/100
Therefore, to find principal
P= I×100/N×R
=400×100/4×5
=40000/20
=2000 rupees
