1.	A sum is split into five equal parts. Each part is lent at annual rate of simple interest of 8%, 7%, 5%, 3% and 2%. They are lent for 1 year, 2 years, 3 years, 4 years and 5 years. On how many parts is the simple interest at least 25% of the total interest?
Answer» 1 2 3 4 Solution :i) LET the total SUM be Rs `5x` ii) `25%` of `5x=Rs(5x)/4`. iii) Find the interest on each sum of Rs `X` using given data, and check which is greater than `(5x)/4`.
