Question

what sum will amount to rs 13986 in 5years at8 percent per anum rate of interest​

Answer 1

Let the sum be Rs P

A=13986

T=5yrs

R=8%p.a.

S.I=A-P= Rs13986-P

Now,S.I.=P×R×T/100

13986-P = P×8×5/100

10(13986-P) = 4P

139860-10P = 4P

139860 = 14P

P = 139860÷14

P= 9990

Thus the sum is Rs 9990
