Missing Number (SSC CGL 2022 Tier -1)

{(1st number + 3rd number) ÷ 5} = 2nd number

(18, 9, 27) → {(18 + 27) ÷ 5} ⇒ 45 ÷ 5 = 9

(40, 36, 140) → {(40 + 140) ÷ 5} ⇒ 180 ÷ 5 = 36

Similarly,

(40, 13, 25) → {(40 + 25) ÷ 5} ⇒ 65 ÷ 5 = 13

Hence, "25" is the correct answer.

[{(1st number - 2nd number) × 8} + 2nd number] = 3rd number

Row 1 →  [{(15 - 11) × 8} + 11] ⇒ {(4 × 8) + 11} ⇒ 32 + 11 = 43

Row 2 → [{(13 - 8) × 8} + 8] ⇒{(5 × 8) + 8} ⇒ 40 + 8 = 48

Similarly,

Row 3 → [{(9 - 7) × 8} + 7] ⇒{(2 × 8) + 7} ⇒ 16 + 7 = 23

Hence, "23" is the correct answer.

{(first num + second num) × 6} = third num

(6, 9, 90) → {(6 + 9) × 6} ⇒ 15 × 6 = 90

(12, 8, 120) → {(12 + 8) × 6} ⇒ 20 × 6 = 120

Similarly,

(13, 6, ?) → {(13 + 6) × 6} ⇒ 19 × 6 = 114

Hence, "114" is the correct answer.

[{(1st number - 2nd number) × 5} + 2nd number] = 3rd number

(12, 7, 32) → [{(12 - 7) × 5} + 7] ⇒ {(5 × 5) + 7} ⇒ 25 + 7 = 32

(17, 13, 33) → [{(17 - 13) × 5} + 13] ⇒ {(4 × 5) + 13} ⇒ 20 + 13 = 33

Similarly,

(14, 8, ?) → [{(14 - 8) × 5} + 8] ⇒ {(6 × 5) + 8} ⇒ 30 + 8 = 38

Hence, "38" is the correct answer.
