Ans 1:

sankalp from Gyan Bharti School, Saket, Delhi
Class : Class 10
Option A is Correct

Ans 2:

Adhrit from CHSV, Chennai
Class : Class 8
This should be A...Agree with Shourya

Ans 3:

Shourya Ganesh from The Green Acres Academy, Mumbai
Class : Class 9
I think it should be A because if you calculate and divide equally then you see that in opt C each bulb gets only power of one and a half dry cell, however in opt A the bulb gets the power of two dry cells. Please rectify SOF

Ans 4:

Akshara from sishya OMR , chennai
Class : Class 8

Ans 5:

sankalp from Gyan Bharti School, Saket, Delhi
Class : Class 10
In option A, the cells are not in the arrangement and the bulb receives current from only one cell

Ans 6:

Yes. the answer should be A. i agree with sourya.

Ans 7:

Shuvangi Das from Vivekananda mission school, haldia

Anushka Wasnik from DPS, nagpur

Aadi from Treamis World School, Bangalore
Class : Class 9
Yes. The answer should be option A, I agree with Shourya

Ans 10:

Aarnav Grover from Anand Niketan Shilaj, Ahmedabad
Class : Class 9
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

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
