Q: Answer-&lt;p&gt;Jolly borrowed some money at compound interest for 4 years. What will be the amount require...

From I SI after 10 years is Rs 1200, so after 1 year 120010 Rs 120 so,SI of 1 year Rs. 120 From III Principal 15 times S.I after 3 years or P 15 times Ptimes R times3100 or R 10045 So from I and II, SI 120 Ptimes Rtimes1100 P times 10045 100 So we can find Principal. then we can find the required amount by CI formula So from I and II, SI 120 Ptimes Rtimes1100 P times 12 100 So we can find Principal, then we can find the required amount by CI formula
