Question

There are two simple interest investment options I and II. The rate of interest in option I is ${4/11}$ times the rate for option II. The time period in option I is 11 times that for the option II. What is the ratio of interest of option I to option II, if the same amount is invested in either?

Ans: a

Let P, R and T have their usual meanings. For option II we have I2 = PRT/100. For option I we have I1 = P × ${4/11} × {R/100}$ × 11 × T. The ratio I1 to I2 is $4/11$ × 11 = 4.
