Question

In four years,6500 ruppes Amounts to 5540 rupees at a certain rate of rate of interest in which time will 1600 ruppes amount to 1816 ruppes at the same rate of interest

Answer 1

Step-by-step explanation:

I =A-P

=6500-5540

=960

I=PxNxR /100

960=5540x4xR/100

R=960x100/5540x4

=4.3pcpa

in second case I=A-P

=1816-1600=210

so

210=1600xNx4.3

so N=210/1600*4.3
