Answer:
16/3
Step-by-step explanation:
Principal=8,000
Amount=10,000
Simple interest=A-P
= 2,000
TIME=4 years
RATE OF INTEREST BE R
R=S.I×100/T×P
=2000×100/4×8,000
=25/4% interest
CASE - 2
PRINCIPAL=4200
AMOUNT=5600
SIMPLE INTEREST=A-P
=1400
RATE OF INTERESTE=16/3%
LET TIME=T
T=S.I×100/R×P
=1400×100/(25/4)×4200
=16/3 years
Therefore and amount of 4200 will amount to 5600 in 16/3 years
