Answer 1

Principal=1250
Rate=4%
Time=x
Amount=1375or P+ SI or
so we have SI = 1375-1250=125
PRT/100=125
= 1250*4*x/100=125
=x*50 =125
x = 2.5 years

Answer 2

Given:
Prinicipal = Rs 1250
Amount = Rs1375
Rate = 4% p. a
Interest = ?
Interest = Amount - Principal
= 1375-1250 = Rs125
Time=?
Time =100XS.I/ PxR
= 100x125/1250x4
=12500/5000
=125/50
=25/10
=2.5 years
= 2 years and 6 months
