17. The simple interest on a sum of money for 5 years at 6% is Rs. 120 more than thesimple interest on the same sum at 5% for 4 years. Find the sum invested.

Answer»

Step-by-step EXPLANATION:

ACCORDING to the problem,

Let SUM be P

R=6%

Time=Tyears

S.I=100P×6×T

S.I=Rs960

100P×6×T=960

P×T=16000----------------(1)

Now For sum

Sum=RsP,R=6%,T=5years

S.I=100P×6×(T+5)=2160

100P×6×T+100P×6×5=2160

10016000×6+100P×30=2160

100P×30=2160−960

100P×30=1200

P=301200×100=Rs.4000

Therefore the Sum is Rs, 4000.
