Ans 4:

Aarnav Grover from Anand Niketan Shilaj, Ahmedabad

It should be C because the ratio of A is that 1 bulb is getting 2 sources, meaning it is 1:2 while in C the ratio is 2:3, and 2 third is bigger than 1 half

Ans 5:

I think the answer is A because if you add 5,6,8,1 the answer is 20 which is a factor of 400 and in the second one it is 18 which is a factor of 324 the the third one should be 12

Ans 11:

nimay gupta from Shiv Nadar School, noida

Yes, as the square root of 400 is 20 and the square root of 324 is 18.
