40 liters of a mixture is created by mixing liquid p and liquid q in the ratio 5 : 3 . how many liters of liquid q must be added to make the ratio 5 : 6 ?
"let x be the amount of liquid q to be added . ( 3 / 8 ) * 40 + x = ( 6 / 11 ) * ( 40 + x ) 1320 + 88 x = 1920 + 48 x 40 x = 600 x = 15 the answer is e ."
subtract(divide(multiply(divide(multiply(add(5, 6), divide(multiply(40, 5), add(5, 3))), 5), 6), add(5, 6)), divide(multiply(40, 3), add(5, 3)))
