Question

if the simple interest on a sum of money at 5% per annum for 3 years is rupees 1200 find the compound interest on the same sum for same period at the same rate

Answer 1

Clearly, Rate = 5% p.a., Time = 3 years, S.I.= Rs. 1200. . .
So principal=RS [100*1200]/3*5=RS 8000
Amount = Rs. 8000 x [1 +5/100]^3 - = Rs. 9261.
.. C.I. = Rs. (9261 - 8000) = Rs. 1261.

Answer 2

Step-by-step explanation:

clearly rate equal to 5% and time is equal to 3 years when principal equal to Rs 100 into 1200 by 3 into 5 equal to Rs 8000 amount equal to Rs 8,000 into 1 + 500 power 3000 into 21 into 21 into 21 by 8000 equal to Rs 9261 equal to Rs 1261
