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 . 78 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 = 78 1 percent for 1 year = 26 = > 100 percent = 2600 answer : b"
multiply(divide(78, 3), const_100)
