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

(45, 9, 12)

(21, 3, 14)

(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 /deleting /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).

(80, 10, 15)

(45, 9, 12)

(21, 3, 14)

The logic Followed here is :

(Ist number ÷ second number) + 7 = IIIrd number

As

(45 ÷ 9) + 7

5 + 7 = 12

And

(21, 3, 14)

(21 ÷ 3) + 7

7  + 7 = 14

Similarly

(80, 10, 15)

(80 ÷ 10) + 7

8  + 7 = 15
