Tank I-

Oil/total volume = 5/13 = 10/26

Tank II-

Oil/total volume = 7/26

resultant ratio of oil to the total volume = x/26

10...........7

........x......

1.............1

(We can mark answer here, Numerator must be multiple of 17 and denominator must not be multiple of 13, C)

resultant ratio of oil to the total volume =

the resultant ratio of oil and water = 17:(52-17) = 17:35
