1.
For this one **I considered the Final exam marks to be 100 So then
** 20% 50% 30%**
** 90% **
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
2.
Over here when you consider the height to be 3x and the base as x u get the ans as C
I assumed the hyp to be 3x then I had to redo it and it was time consuming
Is there any way to do it intuitively atleast for taking the right sides
3.
I did 8H + 12M + 4S = 36 C
36 Cups = part / total = 12/24
then cross multiply to check for 9 cupcakes
4.
I am confused on converting that line to an algebraic expression is it
No of boys leaving = no of girls entering how do I equate it to a ratio
There is no evidence that ABC is a right-angled triangle.
I don’t know what you want from Q3
Let the number of girls that joined be G. We have
\frac{8 + G}{20 - 2G} = \frac{7}{4}
Solve for G. B = 2G.

I did 8H + 12M + 4S = 36 C 36 Cups = part / total = 12/24 then cross multiply to check for 9 cupcakes
I want to know if my approach for Q3 is correct
Your solution sounds convoluted.
I’d just set up a simple relation:
12 cups/36 cupcakes → x cups/9 cupcakes
x = 3
Yes I kno there is no evidence but then in the manhattan they considered it so
A key part of the question is missing in your screenshot:
GMAT Club Forum
U have any idea about the first one?
I know the answer, but I will refrain from giving the answer because I suspect that the question has a flaw.
I had a doubt here so when we dont consider the lowest score we just divide the 3 scores by 4 right
We divide by 3. There are only three quizzes considered in the end.
