What is your subject movement and how much time do you allot to each sub?
I follow -
Chem [35 - max 40 min]
Eng and LR [usually 30-35 min but today I spent too much time here😭]
Maths [I try to attempt at least 25+ ideally 30 and see all the questions till 30 min are remaining for Phy]
Physics [last 30 min, weakest subject, I know Boards level Physics and formulas]

Answer given is

>!P = 4; Q = 3; R = 6 Ans = 13!<

I initially mixed up the answers on P and Q... I've updated it and here's the source

Question is in pg 23 and Solution is in pg 7 RHS
