Missing Number (SSC MTS 2019 Tier-1)

(1st + 2nd + 3rd) ⇒ Total number*3 = (4th number)

7 +6+3⇒16x3 = 48

4+9+8⇒21 x 3 = 63

Similarly, 2+5+7⇒14 x 3 = 42

Hence, "42" is the correct answer.

(1st column + 2nd column + 3rd column) = 4th column

4+ 5+9=18

11 + 6 + 13 = 30

Similarly, 19 + 0 + 3 = 22

Hence, "22" is the correct answer.

(1st row term * 2nd row term - 3rd row term) = 4th row term

7 x 7 - 1 = 48

9 x 5 - 0 = 45

Similarly, 11 x 5 - 1 = 55 - 1 = 54

Hence, "54" is the correct answer.

(1st column + 2nd column + 3rd column)+1 = 4th column

3 + 4 + 9 = 16 + 1 = 17

7 + 2 + 5 = 14 + 1 = 15

Similarly, 6 + 8 + 3 = 17 + 1 = 18

Hence, "18" is the correct answer.

(1st term ) * (3rd term) + (2nd term) = 4th term

3 x 3 + 6 = 15

4 x 2 + 4 = 12

Similarly, 7 x 5 + 2 = 37

Hence, "37" is the correct answer.

(1st + 2nd + 3rd) = total number -1 = 4th term

7 + 8 + 4 = 19 - 1 = 18

2 + 3 + 9 = 14 - 1 = 13

Similarly, 5 + 6 + 8 = 19 - 1 = 18 .

Hence, "18" is the correct answer.

(1st term + 2nd term + 2nd term + 3rd term) = 4th term

6 + 3 + 3 + 8 = 20

11 + 4 + 4 + 7 = 26 ,

Similarly, 9 + 5 + 5 + 1 = 20

Hence, "20" is the correct answer.

In Column

1st + 2(2nd) + 3rd =?

5 + 2(9) + 6 = 29,

3 + 2(4) + 7 = 18

Similarly, 1 + 2(9) + 3 = 22

Hence, "3" is the correct answer.

(1st row term + 2nd row term + 3rd row term) ⇒Total number = 4th row term

9 + 6 + 4 ⇒ 19 x 2 = 38

3 + 2 + 5 ⇒ 10 x 2 = 20

Similarly, 7 + 8 + 3 ⇒ 18 x 2 = 36

Hence, "36" is the correct answer.

(First number)+(Second number)+(Third number)⇒(total number)*3= 4th number

7 + 6 + 3 ⇒16 x 3 = 48

4 + 9 + 8 ⇒ 21 x 3 = 63

Similarly, 2 + 5 + 7 ⇒ 14 x 3 = 42

Hence, "42" is the correct answer
