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 7:

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 18:

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.
Ans 29:
Class : Class 6
The answer is D(8) because if we look at the V from a Tilted angle then it is a 90 degree angle. 4 V4 right angles4 4= 8
Ans 30:
Class : Class 6
IT IS 12
Ans 31:
Class : Class 8
How ??
Ans 32:
Class : Class 6
THE ANSWER IS 12 AS IF YOU LOKE AT ACUTE ANGLES IN THE EXTERIOR YOU CAN SEE 2 RIGHT ANGLES
Ans 33:

4
Ans 35:
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.
