if 1.5 x = 0.04 y then the value of ( y - x ) / ( y + x ) is
x / y = 0.04 / 1.5 y / x = 1.5 / 0.04 by componendo dividendo rule ( y + x ) / ( y - x ) = 1.54 / 1.46 ( y - x ) / ( y + x ) = 1.46 / 1.54 = 73 / 77 answer : b
divide(subtract(divide(multiply(1.5, const_100), const_2), const_2), add(divide(multiply(1.5, const_100), const_2), const_2))
