Select the set in which the numbers are related in the same way as are the numbers of the following set.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed).

(56, 22, 26)

(34, 20, 18)

(78, 54, 44)

(56, 22, 26)

(34, 20, 18)

The logic followed here is :

(Ist number +second numbe )÷ 3  = IIIrd number

as

(56 + 22)  ÷ 3 =26

(34 + 20)  ÷ 3 =18

same as (78, 54, 44)

(78 + 54)  ÷ 3 = 44
