Missing Number (SSC CPO 2019 Tier -1)

(First column term + Second column term)*2 = (Third column term)

1st Column: 3 + 14 = 17 × 2 = 34

2nd Column 18 + 13 = 31 × 2 = 62

3rd Column angle 27 + 22 = 49 × 2 = 98

Hence, "22" is the correct answer

In the first column,

(48 - 28)= 20 × 3 = 60

Similarly. (65 -71)= 6 × 18 = 108

(? - 35 )×7=98 ⇒ ?=21

So the answer will be 21.

Hence, "21" is the correct answer.

First number/Second number =Fourth number /Third number

18/ ? = 9/2 ⇒ ?=4

So the missing number is 4.

In the first Column, Square of 4 ^ 2 + 3 = 16 + 3 = 19;

In the second Column, square of 18 ^ 2 + 6 = 324 + 6 = 330;

So, in the 3rd Column, 23 ^ 2 + 1 = 529 + 1 = 530

Hence, "530" is the correct answer.

(Logic is (In row) :- (First number x Third number) - Third number = second number

15*14 ⇒ 210 - 14 =196

7*16 ⇒ 112 - 16 = 96

255=(18x)-x ⇒ x = 255/17 = 15

So, the missing number is 15.

Logic:- In each column (first number x third number) + fourth number = second number. Similarly, in the 3rd column,

(8x ?)+48=64 ⇒ ?= 16/8 = 2

Hence, "2" is the correct answer.

In the first row, 3 ^ 2 + 2 ^ 2 + 5 ^ 2 = 9 + 4 + 25 = 38

In the 3rd row, 7 ^ 2 + 1 ^ 2 + 2 ^ 2 = 49 + 1 + 4 = 54

Similarly, in the 2nd row, 5 ^ 2 + 3 ^ 2 + 4 ^ 2 = 25 + 9 + 16 = 50

Hence, "50" is the correct answer.

Logic: In each row n : 3 n + 1 = m / 3 m + 1

As, 7 x 3 + 1 = 22 , 22 x 3 + 1 = 67 and so on.. So, answer is 52 x 3 + 1 = 157

Hence, "157" is the correct answer.
