two vessels contains equal number of mixtures milk and water in the ratio 3: 2 and 4: 1. both the mixtures are now mixed thoroughly. find the ratio of milk to water in the new mixture so obtained?
divide(add(multiply(3, divide(add(4, 1), add(3, 2))), 4), add(multiply(2, divide(add(4, 1), add(3, 2))), 1))
"the ratio of milk and water in the new vessel is = ( 3 / 5 + 4 / 5 ) : ( 2 / 5 + 1 / 5 ) = 7 / 5 : 3 / 5 = 7 : 3 answer is d"
