Answer 2

Given :- Which number replace the question mark (?) .

7122, 6521, 8332, 4743, 9911, 387? .

Solution :-

Logic :- sum of digits is increasing by 2 .

Explanation :-

Let us assume that number x will replace question mark (?).

→ 7122 = 7 + 1 + 2 + 2 = 12.

→ 6521 = 6 + 5 + 2 + 1 = 14.

→ 8332 = 8 + 3 + 3 + 2 = 16.

→ 4743 = 4 + 7 + 4 + 3 = 18.

→ 9911 = 9 + 9 + 1 + 1 = 20.

Therefore, sum of the last number will be 22 .

→ 387x = 3 + 8 + 7 + x = 22

→ 18 + x = 22

→ x = 22 - 18

→ x = 4 (Ans.)

Hence, Number 4 will replace question mark (?).
