statement 1- The definition of perfect number on google is the same as the definition of perfect number provided by the question as for statement 2 eg 6 and 4 is divisible by 2 so 6 4= 10 div by 2 and 6-4= 2 also div by 2. so people who say answer is b c or d are complete idiots

The answer can only be C. For the first statement, If you take an example as 6, it will be 1 2 3=6 which means statement 1 is false as it is written that it should be double. Statement 2 is true. For example, take 25 and 20 and the number as 5. 25 20=45(Divisible by 5) and 25-20=5(Divisible by 5)

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!
