1.	Rs. 2800 was split into two parts. One part was lent at 20% per annum simple interest for 10 years. The other part was lent at 25% per annum simple interest for 20 years. Each part yielded equal interest. Find the lower part (in Rs.).A. 800B. 900C. 1000D. 1200
Answer» Correct Answer - A Let the one part be Rs. X. `therefore` The other part would be Rs. (2800-x). `((x)(10)(20))/(100)=((2800-x)(20)(25))/(100)` `implies 2x=5(2800-x)` x=2000 `therefore` The lower part =2800-x =800.
