Questions below followed by three quantities. Find the relation between them.
Quantity I: Ratio of CI earned only for 3rd year to CI earned only for 2nd year on an amount Rs. X at R% per annum is 11/10 and CI earned on Rs. (X + 1500) in 2 years at the same rate is Rs. 1890. Find the value of X?
Quantity II: A man invested Rs. 7000 in scheme A at SI for 5 years at 16%, the interest he obtained is divided into equal halves and invested in two different schemes i.e. scheme B and scheme C for 2 years each at CI at 10% and 13% respectively. Find total interest obtained in scheme B and C.
Quantity III: If a sum is invested in Scheme Q at CI, then amount obtained after 2 years from this Scheme is 1.69 times the sum invested. Rate of CI for scheme P is half of the rate of CI for scheme Q. Find out the interest earned when Rs. 10,000 was invested for 2 years in scheme P at CI.
