Question

In what time will 6880amount to 7224,if simple interest is calculated at 15%per annum

Answer 1

Answer:

3 years where interest is 344Rs.

Answer 2

let the s.i be- 344 (7224-6880=344)

principle = 6880

rate of interest = 15% p.a

time = x

therefore time = 100×s.i/p × r

time = 100×344/6880×7224

time = 1/3 years ( 4 month's )

Therefore ANSWER = 1/3 YEARS

checking

6880×15×1by3×1by100

= 344 ( s.i )

amount = 6880 + 344

= 7224
