The missing number is 1164.

Here, 1164 ÷ 3 - 14 * 2 + 12 

= 388 - 14 * 2 + 12 

= 388 -28 + 12

= 400 - 28

= 372

If m=6, n=4, p=3, then the equation becomes 10 x 62 – 16 X 4 + 2 X 3 + 5 = 10 X 36 – 64 + 6 + 5 = 360 – 64 -11 = 360 – 75 = 285

Ans 2:

Class : Class 10
its not 285 but its - 285

In first one, middle figure go to the bottom right corner, bottom right corner figure go to upper left corner , upper left corner figure go to middle and upper right and bottom left figure just change their places. So, if the same rule is used in figure 3 and 4, the answer is c.

Can you show where is symmetrical line in "D" that means 9

Ans 3:

Class : Class 4
It would be (5) because it is only a prime number.

Ans 4:

Class : Class 8
it is D and C as 8 is Symmetrical and others are not and 2 3=5, 5 3 = 8, 8 3=11 but the last option is 9 and 8 1=9

Ans 5:

Class : Class 8
all the gaps are =plus signs

Ans 6:

Class : Class 4
Only 8 has a line of symmetry

Ans 7:

Class : Class 4
Here 2 3=5 and if we continue like this then 5 3=8 and 8 3=11 so, 9 is the odd one out and "D" is the correct answer.

Ans 8: (Master Answer)

Class : Class 1
Here, the figure in option 'C' is only symmetrical while the rest of the figures are not symmetrical. Hence, figure in option 'C' is the odd one out of all the four figures.

Ans 9:

Class : Class 4
