which number completes the puzzle ?

Answer : 29

In each diagram multiply top two values and add their sum to give the bottom value.

In first rectangle, (6 * 4 ) + (6 + 4) = 34

In second rectangle,  ( 8 * 5 ) + (8 + 5) = 53

Similarly, in last rectangle, (9 * 2) + (9 + 2) = 29

Find missing number in this rectangle filled with numbers.

Answer : 6

Find the difference of first two numbers in each row and double it to get third number in that row.
11-2 = 9*2 = 18
5-2 = 3*2 = 6
12-5 = 7*2 = 14
So, answer is 6.

All three triangles are interconnected. Find the answer by deriving a relation between them.

Answer : 10

Difference of numbers in first two pentagons is in third pentagon at same location.

difference of
2,5 = 3
4,5 = 1
7,9 = 2
6,11 = 5
1,10 = 9

ind the missing number in last rectangle with help of other three rectangles.

Bottom right rectangle contain result of sum of numbers in first three rectangles at respective positions.

6+3+3=12
4+1+12=17
9+4+3=16
2+7+6=15

So, answer is 15.

Replace the question mark with appropriate number.

Answer : 2

Sum of numbers on each line is 15.

6+5+4 = 15

3+5+7 = 15

9+5+1 = 15

8+5+2 = 15

So, answer is 2.

Find missing number in this tricky number sequence puzzle

Answer : 36

Multiply first two numbers in each row and subtract first number from the product to get third number in that row.

(2*11)-2 = 20
(4*9)-4 = 32
(7*8)-7 = 49
(4*10)-4 = 36

So, answer is 36.

It is little bit difficult to guess the number in last rectangle.

Answer : 8

In each rectangle, multiply first row numbers and subtract sum of numbers in second row from it. Result of each rectangle should be 40.

(13*5)-(5+20) = 40
(12*4)-(3*5) = 40
(16*4)-(20+4) = 40
(11*5)-(7+8)= 40

So, answer is 8.

Answer : 2

9/3 = 3;

6/2 = 3;
8/4 = 2;

Find the missing number which comes at the end of this table and replaces question mark.

Answer : 4

Calculate the difference of numbers in each row. it follows a particular sequence like 6,5,4,3,2,1.

8 – 2 = 6
9 – 4 = 5
7 – 3 = 4
9 – 6 = 3
8 – 6 = 2
4 – 3 = 1

So, answer is 4.

Based on the pattern which numbers are following in first three rectangles, calculate the missing number in fourth rectangle.

Answer : 2

Multiply two numbers in first row in each rectangle and put that whole number in next row.

7 * 4 = 28
6 * 5 = 30
2 * 9 = 18
4 * 8 = 32
So, answer is 2.

Find the missing number in this vertical table

Answer : 10

Add numbers in each row and result is same as left number in next row.

1 + 1 = 2
2 + 1 = 3
3 + 2 = 5
5 + 1 = 6
6 + 4 = 10

So, answer is 10.
