Question

If 900 Rs. amounts to 1044 Rs. in 4 years, what sum will amount to Rs. 1368 in 3 and a half years at the same rate?

Answer 1

Answer:

If the amt is compounded annually(C.I.),

final amt=sum(1+(r/100))4

therefore,  1044=x(1+(4/100))4

sum=Rs. 892.41

---------------------------

If it is S.I.,

final amt=sum+ (sum*r*time/100)

therefore, 

1044=x + (x*4*4/100)

sum=Rs 900
