Select the triad in which the numbers are related in the same way as are the numbers of the following triads.
5-70-9
8-95-11
(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)

Correct option is C

Logic: II number = (I number + III number) × 5
5 - 70 - 9
​ (5 + 9) × 5 = (14 × 5) = 70
8 - 95 - 11
(8 + 11) × 5 = (19 × 5) = 95
By using option (c)
6 - 135 - 21
(6 + 21) × 5 = (27 × 5) = 135
