Missing Number (SSC CGL 2019 Tier -1)

21 - 6 = 15 ×2 = 30

49 - 5 = 44 × 2 = 88

In column i ⇒ 10(15 - 14) = 10

in column ii ⇒4(7 - 3) = 16

In column iii ⇒ 7x (8-6)=14

In column iv ⇒5(25 - 12) = 65

In 1st column, 8 ×4 = 32

32-3=29

In second column, 11 x 7=77,

77-6=71

Similarly,

In third column, 14 × 5 = 70

70-3=67

9×4 = 36 - (9 + 4) = 36 - 13 = 23

Similarly: 11× 7=77-(18)=59

Similarly, 12 ^ 2 - 5 ^ 3 = 19, 18 ^ 2 - 6 ^ 3 = 108

Row 1 ⇒ 11 + 2 = 13, 13 + 4 = 17

Row 2 ⇒ 33 + 2 = 35 ,35+4=39

Similarly,

Row 3⇒  189+2=191, 191+4=195
