The simple interest on a certain sum is `(16)/(25)` of the sum. If the rate percent annum and the time are numerically equal, then the rate percent is (a) 8% (b) 4% (c) 6% (d) 12%

The simple interest on a sum of money is (4)/(9) of the principal.Find the rate percent and time, if both are numerically equal.

The simple interest on a certain sum of money is 3/8 of the sum in 6""1/4 years. Find the rate percent charged.

The simple interest on a sum of money is (8)/(25) of the sum. If the number of years is numerically half of the rate percent per annum, then find the rate percent per annum.

Simple interest on a certain sum at a certain annual rate of interest is (1)/(9) of the sum.If the numbers representing rate percent and time in years be equal,then the rate of interest is 3(1)/(3)% (b) 5% (c) 6(2)/(3)% (d) 10%
