UY : PT :: KO : ? U = 21, Y = 25: P = 16, T = 20:: K = 11, O = 15: ?? (21)(25):(16)(20)::(11)(15): ?? Difference between 21 and 11 = 10 and 25 - 15 = 10 Therefore the 1st number will be 16 - 10 = 6(F) As, 21 + 4 = 25, and 16 + 4 = 20, and 11 + 4 = 15, in the same way 6 + 4 = 10(J) Therefore, the answer is as follows: UY : PT :: KO : FJ
