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 : D

Explanation

From figure it can be seen that 231 - 36 = 195, 195 - 36 = 159 and 159 - 36 = 123. Therefore missing number is 159.

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 : D

Explanation

We have 23 - 6 - 8 = 9, 13 - 2 - 7 = 4. Similarly 15 - 1 - 4 = 10. Hence missing number is 01.

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

We have $\frac{22+24}{2} = 23$ and $\frac{36+18}{3} = 18$, similarly $\frac{56+32}{8} = 11$.therefore missing number is 8.

Answer : C

Explanation

We have (4-1) + 2 = 5 and (11-2) + 2 = 11, in this way (17-9) + 2 = 10.

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 : C

Explanation

The numbers are obtained from top to bottom as $6^2 +6^2+1 = 73$ and $5^2 +2^2 +1 = 30$, similarly $1^2 + 4^2 +1 = 18$. Hence 1 is missing number.

Answer : C

Explanation

The number are obtained by dividing the pair of numbers by 5, 4, 3, and 2 in clockwise direction and added as $\frac{55}{5} + \frac{10}{5} = 13, \frac{20}{4} + \frac{12}{4} = 8, \frac{22}{2} + \frac{56}{2} = 39$, therefore missing number can be calculated as $\frac{39}{3} + \frac{24}{3} = 21$. Other numbers in the rhombus are obtained by addition of numbers around as 55 + 20 = 75 and so on.
