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

(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.)

(5, 60, 70)

(9, 108, 126)

(7, 84, 98)

(5, 60, 70)

(9, 108, 126)

The logic followed here is :

IIIrd number - 2 × Ist number = second number

As

70 - 2 × 5 = 60

126 - 2 × 9 = 108

Same as in (7, 84, 98)

98 - 2 × 7 = 84
