ji mam and mam key scoring are last 5 day jispe krna cahiye ??
Key scoring ??
Sorry dint get
means main scoring topic mam
Rearrangement can be. That is to find the odd sentence.
Fill in the blanks if come.
Then uske bad depends ki konsa topic apka strong hai
kk ty mam
New pattern b practice karo
N new pattern aaega to cutoff English ki kam hi jaegi to attempt accordingly. Ki negative me na chla jae score

Yes.
Tell me what u dint get. Then i ll explain accordingly
mam 9th q m option E bhi toh ho skta h if the value of x = -20/4 & 3/4 and the value of y = 8/4 & -5/4 …..plz check it once as i have taken 1st eqn as -20 and +3 ….plz tell
-20 * +3 = -60
but it should be +60 na
kk mam now i understood 🙂
