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