a sum was put at simple interest at certain rate for 3 years . had it been put at 1 % higher rate it would have fetched rs . 75 more . the sum is : a . rs . 2,400 b . rs . 2,100 c . rs . 2,200 d . rs . 2,480
"1 percent for 3 years = 75 1 percent for 1 year = 25 = > 100 percent = 2500 answer : a"
multiply(divide(75, 3), const_100)
