in a can , there is a mixture of milk and water in the ratio 4 : 3 . if the can is filled with an additional 10 liters of milk , the can would be full and the ratio of milk and water would become 5 : 2 . find the capacity of the can ?
let c be the capacity of the can . ( 4 / 7 ) * ( c - 10 ) + 10 = ( 5 / 7 ) * c 4 c - 40 + 70 = 5 c c = 30 the answer is d .
add(add(multiply(divide(multiply(2, 10), subtract(multiply(3, 5), multiply(2, 4))), 4), 10), multiply(divide(multiply(2, 10), subtract(multiply(3, 5), multiply(2, 4))), 3))
