sankalp from Gyan Bharti School, Saket, Delhi
Class : Class 9
Option A is Correct

Ans 11:

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 12:

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
