Ans 4:

Class : Class 6
On the outside, we see 4 right angles easily. But if you turn your device 90 degrees left/right, you will see that the angle formed by the sharp edges of the figure also measures 90 degrees. It is just not visible due to the angle you look at it.

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 32:

Class : Class 7
It is Eight . If you tilt the small angles you will notice that there are eight right angles

Ans 33:

Class : Class 8
Actually it should be 4 or 12

Ans 34:

Class : Class 5
confusing but obvious

Ans 35:

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

Ans 36:

Class : Class 4
there cannot be 8

Ans 37:

Class : Class 9
it cannot be 8 at all costs

Ans 38:

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

Ans 39:

Class : Class 6
I think soumyaraj Roy is correct as there are no other angles that are exactly 90 degrees.

Ans 40:

Class : Class 7
The answer is 4 definitely!

Ans 41:

Class : Class 6
No, it is 8. You can see 4 of them easily. The other four are hidden between the sharp edges of the figure. Tilt it 2 find out.
