Missing Characters Online Quiz

Answer : C

Explanation

The numbers are changing as follows

0 + 2 = 2

2 + 4 = 6

6 + 6 = 12

12 + 8 = 2042 + 14 = 56

Answer : C

Explanation

Difference of all pairs of numbers i.e. 12 - 9 = 3, 6 3 = 3, 11 - 8 = 3,and 16 13 = 3. Hence missing number is 13.

Answer : C

Explanation

It can be seen that 819 is the combination of squares of 3 and 9, hence 2 is the missing number.

Answer : A

Explanation

All numbers in the figure are related to each other as,(19 + 1)(19 - 1) = 360 and (12 + 3)(12 - 3) = 135, similarly (13 + 5)(13 - 5) = 144. Hence missing number is 144.

Answer : D

Explanation

We have 4 + 3 + 1 + 1 = 9 = 8 + 1 and 1 + 2 + 4 + 6 = 13 = 4 + 9, similarly 8 + 7 + 0 + 3 = 18 = 9 + 9. Hence missing number is 3.

Answer : C

Explanation

The numbers are related as, (3-2) + (1-0)= 2+6 =8 and (10-4)+(6-5) = 0+7 = 7, similarly (8-7)+ (12-9) = 4+7 = 11. Hence missing number is 11.

Answer : A

Explanation

The numbers are obtained as 7² = 49 and 5¹= 5, similarly 79⁰= 1.

Answer : A

Explanation

The summation of all numbers when divided by 3 resulting a number at the centre as, $\frac{51+11+22+21}{3} = 35$ and $\frac{1+51+2+24}{3} = 29$, similarly $\frac{45+18+63+9}{3} = 45$. Hence missing number is 9.

Answer : A

Explanation

Each column consists of numbers that belong to certain category. From the figure it is clear that 1^st column has prime and 2^nd column are even number and also it is clear that 3^rd column consists of odd numbers which are not prime. Thus 51 is the missing number.

Answer : C

Explanation

We have $\left ( \frac{14}{2} \right ) \left ( \frac{4}{2} \right )\left ( \frac{6}{2} \right ) = 723 =327$, similarly$ \left ( \frac{10}{2} \right ) \left ( \frac{8}{2} \right ) \left ( \frac{2}{2} \right )= 541 = 145$. Therefore it is clear that 2 is the missing number.
