It is D because 11 6=17and 17x17 is 289.

Letâs see what pattern is being followed by the numbers in the above grid. Letâs take the first column â 7, 81, 2 If we add 1st and 3rd number = 7 2 = 9 And if we multiply 9 by 9 itself = 9 x 9 = 81. 81 is the 2nd number in the first column. Letâs see if the numbers in second column follow the same pattern. 9, 169, 4 We add 1st and 3rd number = 9 4 = 13 We multiply 13 by 13 itself = 13 x 13 = 169. 169 is the 2nd number in the second column. That means the numbers of third column will follow the same pattern. 11, ?, 6 We add 1st and 3rd number = 11 6 = 17 We multiply 17 by 17 itself = 17 x 17 = 289. 289 will be the missing number in the third column. So, the correct answer is Option D.

option C is the answer as when you fold each of the other figures (opt. a, b, d), you will get the same cuboid as asked in the question. But in the third option, when you fold the figure along the lines, you will get a cuboid whose one face is missing..... So, this is the explanation :)

Ans is C because the arrow is facing just after 2 small lines from 25 kg.

Aditya that is the very reason why it will be a unique triangle and option C is correct since it an angle such as that can be created by bisecting 60 degree three times

## Ans 3:

Class : Class 5
The option b states that a unique triangle is constructed and it is possible to do so. However option c states that we CANNOT construct the angle 7.5. This is false cause it can be constructed by bisecting an angle of 60, three times.

ans is b.i agree with aditya

Class : Class 7
I mean B

## Ans 8:

Class : Class 7
both B and C are correct as angle 7.5 can be constructed using compass and ruler and we cant construct a unique triangle with only 3 angles given.

## Ans 9:

Class : Class 8
ya guys the answer is D

## Ans 10:

Class : Class 8
Answer is b as the length of sides of triangle are variable and therefore unique triangle cannot be constructed

## Ans 11:

Class : Class 7
It is meant to be c

We first need to multiply, then he is telling that he threw 18 of them so, you just need to subtract it from the total number of apples! Then it tells that it is put into 8 boxes so, just divide!
