Select the option in which the numbers share the same relationship as that shared by the given pair of numbers.

(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 1and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

33 : 340

48 : 490​​

Given: 

33 : 340

48 : 490​​

Logic: (1st × 10) + 10 = 2nd 

Checking given pairs:

33 → 340 → (33 × 10) + 10 = 340 

48 → 490 → (48 × 10) + 10 = 490 

Checking options:

A) 31 → 279 → (31 × 10) + 10 = 310 $$\neq$$ 279​

B) 44 → 460 → (44 × 10) + 10 = 450 $$\neq$$ 460​

C) 63 → 640 → (63 × 10) + 10 = 640 (Follows)

D) 27 → 270 → (27 × 10) + 10 = 280 $$\neq$$ 270​

Thus, correct option is (c).
