1 2 3
2 4 6
3 6 ?
Answer is 9.
How?
Here, every element in second row = corresponding column element in first row * 2.
Similarly every element in third row = corresponding column element in first row * 3.
50
20 40
90
30 10
?
Answer is 30.
How?
Sum of the numbers on vertices of a triangle should be 90, i.e. 20 + 40 + ? = 90 => ? = 30.
4
6 2
9 3 1
19 10 7 ?
Answer is 6.
How?
Here, Number in a block is sum of the number on the top and right block so 7 = 1 + ?, hence ? should be 6.
1 ? 12 11
6 7 14 13
8 5 10 15
4 2 9 3
Answer is 0 OR 16.
How?
Here, there is no special pattern except that they are continuous numbers which are jumbled up, so the missing number can either be 0 or 16.
5 13 8 # 11 11 # 6 ? 3
Answer is 9.
How?
Here, every middle element is the sum of the other two so answer should be 6+3 = 9.
If,
1 = 5
2 = 25
3 = 325
4 = 4325
Then, 5=….. ?
Answer is 54325
How?
Just keep appending the new number to the previous answer 🙂
6 – 1 x 0 + 2 / 2 = ?
Given
6 – 1 x 0 + 2 / 2
= 6 – 0 + 1
= 7
IF 11*11 = 4, 12*12 = 9, Then 13*13 = ?
Given
11×11 = (1+1)*(1+1) = 4
12×12 = (1+2)*(1+2) = 9
13×13 = (1+3)*(1+3) = 16
IF 1 =2, 4 20, 6 =42, 9=90, Then 10 =?
Given 1 = 1^1 + 1,
4 = 4*4 + 4 = 20
6 = 6*6 + 6 = 42
9 = 9*9 + 9 = 90
10 = 10*10 + 10 = 110
IF 1 = 5, 2 = 11, 3 = 36, 4 = 150, Then 5 = ?
Given 1 = 5,
2 = 5*2 + (1) = 11
3 = 11*3 + (1 + 2) = 36
4 = 36*4 + (1 + 2 + 3) = 150
5 = 150*5 + (1 + 2 + 3 + 4) = 760
