[asadalam]

Bachey relax kar rahy hain.

To kia ab so bhi na,neend seedhay dimagh k liay zaroori hai,aur maths k liay seedha dimagh zaroori hai.

 

[Faizan Muhammmad]

Admit it, it waas DHOKA

nope
it was legit

 

[funky brat]

The last 2 parts, I think I'm making some stupid mistake again.
bii) PU= PQ+QU
3 and -9 + 7 and 2= 10 and -7. But the answer in MS is 10 and 7. Someone explain.
b iii)
QS= QP+PS
-3 and 9 + 17 and k= 14 and 4 (QU= 7 and 2 so it's twice)
so k according to me is 13 but it is -5 in the MS. Please help :/

yeah you are subtracting the upper value from lower adn vice versa
-9 +7 nae, 3+7 hona hai

@ Faizan like karnay ka bohat shukriya. -.-

Yeah but I'm talking about that 7 part in the answer.

I'm not doing that.

It 3+7 and -9+2=That gives 10 and -7

Whats so hard about that?

 

[funky brat]

It 3+7 and -9+2=That gives 10 and -7

Whats so hard about that?

THE THING IS IDK WHAT IS 10 AND -7.
THE ANSWER IN THE MS IS 10 AND 7. I REPEAT 7. SHOULD I COME AGAIN? 7, A POSITIVE SEVEN.

 

[asadalam]

Please. :/

Second one:
-3+17=14
9+K=4

Rearrange nd K will become -5

Add QP + PS and then compare with QU to get a factor of 2 to multiply with.

 

[Faizan Muhammmad]

Please. :/
