2018 : 22 :: 2022 : ?

Correct Answer: (b) 12
Solution:

(digit sum of first num) × 2 = second num
2018 : 22 ⇒ 2 + 0 + 1 + 8 = 11 × 2 = 22
Similarly,
2022 : 12 ⇒ 2 + 0 + 2 + 2 = 6 × 2 = 12

MJ : HE :: GW : ??

Correct Answer: (d) BR
Solution:

MJ ⇒ M - 5 = H and J - 5 = E
Similarly,
GW ⇒ G - 5 = B and W - 5 = R

1053 : 18 ⇒ 1 + 0 + 5 + 3 = 9 × 2 = 18
Similarly,
2354 : 28 ⇒ 2 + 3 + 5 + 4 = 14 × 2 = 28
