rs . 900 becomes rs . 956 in 3 years at a certain rate of simple interest . if the rate of interest is increased by 4 % , what amount will rs . 900 become in 3 years ?
"solution s . i . = rs . ( 956 - 900 ) = rs . 56 rate = ( 100 x 56 / 900 x 3 ) = 56 / 27 % new rate = ( 56 / 27 + 4 ) % = 164 / 27 % new s . i . = rs . ( 900 x 164 / 27 x 3 / 100 ) rs . 164 . ∴ new amount = rs . ( 900 + 164 ) = rs . 1064 . answer c"
add(900, divide(multiply(multiply(900, add(divide(multiply(subtract(956, 900), const_100), multiply(900, 3)), 4)), 3), const_100))
