Misc2 Quant


I tried using the property of inscribed and central angle but that doesnt give me the ans


Hw do I go abt this? Under time constraint I cud not solve this problem

which is the algebraic method of solving this


How I find the even factors

For first question : Side angle side triangle - #4 by HoldMyBeer

Thanks
cud you explain the 2nd and third one

It will not really help you if I just explain them! Try to tackle them, google stuff, check answers and then try to back-solve them :-> Doing it this way will force your brain to think in a critical manner which is very important because u need to develop a habit of coming up with intuition on what strategies work on a particular type of question.(No one can teach you that )

Reading solutions most of the time just creates a false sense of feeling that you’ve understood the the topic, which cause a great harm in the real test !

Sure I will do this

For this one **
I considered the Final exam marks to be 100
So then
** H Q FE

** 20% 50% 30%**

** 90% **
**Score 18/20 **

For quiz if I remove 13 then wud it be 17+15+19=53
Then calculate 53/60 and then find 88% of 50
But then I get the ans as 28

when I solve the eq
18 + 44 + x = 90

That question is ambiguous; I’ve flagged it.

what

2^x - 2^y = 960 \\ 2^{y}(2^{x-y}-1) = 2^6(15)\\ 2^{y}(2^{x-y}-1) = 2^6(2^4 - 1)\\ \therefore y = 6,\ x - y = 4 \\ => x = 10\\ A) 10 - 6 =4\\ B) 5\\ A < B

Thank you :smiley:
