Question

Rs. 6400 amount to Rs. 6848 in 2 years at simple interet. What wii Rs. 8000 amount to in 3 years at the same rate of interest​

Answer 1

Principal = 6400
Amount = 6848
SI = A - P
=> 6848-6400
=> 448
R = SI × 100/ P × T
=> 448×100/6400×2
=> 44800/12800
=> 448/128
=> 3.5 %
Rate = 3.5

According to the question :-
given ,
Principal = 8000
Time = 3 year
Rate = 3.5%
SI = 8000×3×3.5 /100
=> 240×3.5
=> 840
Amount = P + SI
=> 8000+840
=> 8840

Amount = Rs. 8840
