1. Simple Interest SI = 200, Rate R = 10, Time T = 2 Years, find P
Solution:
Simple Interest `SI=200`
Rate of interest `R=10%`
Time `T=2` year
Find `P`
We know that
`SI=(P*R*T)/100`
`:.P=(SI xx 100)/(R xx T)`
`:.P=(200 xx 100)/(10 xx 2)`
`:.P=1000`
2. Simple Interest SI = 750, Rate R = 5, Time T = 3 Years, find P
Solution:
Simple Interest `SI=750`
Rate of interest `R=5%`
Time `T=3` year
Find `P`
We know that
`SI=(P*R*T)/100`
`:.P=(SI xx 100)/(R xx T)`
`:.P=(750 xx 100)/(5 xx 3)`
`:.P=5000`
3. Simple Interest SI = 1200, Rate R = 6, Time T = 1 Years, find P
Solution:
Simple Interest `SI=1200`
Rate of interest `R=6%`
Time `T=1` year
Find `P`
We know that
`SI=(P*R*T)/100`
`:.P=(SI xx 100)/(R xx T)`
`:.P=(1200 xx 100)/(6 xx 1)`
`:.P=20000`
