I am confused what is the answer because some are saying a , some are saying b ,some are saying c and some are saying d .

Class : Class 9

## Ans 11:

Class : Class 7
According to me, A is the correct answer.

Class : Class 6

Class : Class 8
b is correct

Class : Class 6

Class : Class 8
its b

## Ans 16:

Class : Class 6
according to me , its B as if two numbers are divisible by a number , their sum and difference is not divisible by the same number . For example : 2

Class : Class 7
a is correct

## Ans 18:

Class : Class 9
According to me ,it is C

## Ans 19:

Class : Class 6
it should be A because if we take 39 and 26 as multiples and 13 as factor then 39-26=13. which is divisible by 13

Class : Class 6

## Ans 21:

Class : Class 6
its b because say if you take 6,and you say 2 and 3 are divisible by it. then they are saying that their sum and diff is also divisible but 2 3 is 5 which is not divisible by 6

the angles are 80 degree and 100 degree. Method- 4:5=4x and 5x , 4x+5x=180 , 9x=180, x=180/9, x=20, therefore, 4:5= 4*20and 5*20 4:5=80 and 100

## Ans 2:

Class : Class 7
80,100

Very good Nilarka Pahari and Khushie. Friends , the correct answer is B only. Just try to see . Tilt your head to your right and try to see the cuts at the end of the ribbons . You will find the error of your own. Did you find that? I know that only 5 to 37 percent of you can nfind the eight angles. Be very accurate and intelligent. I also did the same mistake while giving the test . Please look carefully!

## Ans 9:

Class : Class 8
It cannot be 8 at all costs There is an error in this question

Class : Class 5

Class : Class 7

## Ans 12:

Class : Class 4
No ,the answer is 8 because those small angles are also right angle

## Ans 13:

Class : Class 4
Look closely. The answer is 8. If you look at the cuts in the ribbon which looks like a V at the top, you can see the right angle by tilting your device. Same follows with the other cuts
