two pipes a and b can fill a tank in 24 and 48 minutes respectively . if both the pipes are used together , then how long will it take to fill the tank ?
"part filled by a in 1 min . = 1 / 24 part filled by b in 1 min . = 1 / 48 part filled by ( a + b ) in 1 min . = 1 / 24 + 1 / 48 = 1 / 16 . both the pipes can fill the tank in 16 minutes . answer : b"
add(multiply(24, const_100), multiply(multiply(subtract(const_1, multiply(add(divide(const_1, 24), divide(const_1, 48)), const_2)), 24), const_60))
