Can anyone solve this problem in short method.
Question : A mixture contains milk and water in the ratio 7.5 . If 264 ml of mixture is taken out and 74 mil of milk and 158 ml of water is added into remaining mixture,then the quantity of water in the resultant mixture is the 12.5% more than that of water . What is the original quantity of mixture

Is this correctly worded? Like what does this mean - "quantity of water in the resultant mixture is the 12.5% more than that of water"?

I agree. I think there’s some typo here

hello, I was doing an official test and I found one question very hard that I’m not able to solve it still now, I show you the track. Hopefully, someone can explain to me how to do it

Hi. You can search - likely someone ran into the same issue but you are not allowed to post questions from the Actual GMAT exam.

ofc sorry for the incomprehension, it’s not the actual test its the simulation 1 of the starterkit

You want to check your question.
1) Ratio should be 7:5
2) Is the resultant mixture containing 12.5% more water than original water amount or?
3) This is NOT a GMAT Question in my opinion. This is too hard/too many calculations for a 2-min question.

Oh, then sure. You can post your question or search for the discussion as it may likely exist.

Price of an object increase by 25% and become $100. Find the original price.

100/1.25 = 100x4/5 = 80

Can you send it written from of the question as I can’t see the picture you sent

hey, lets simplify this.. pick 3 places first, we need such that x+y=x+y... where x, y, and x+y lies in the range of 1 to 9... make all cases using x+y = 2-9 (note that the min value will be 1+1 = 2, and max be 4+5=9), as you will write these cases, you will observe a pattern as well... which will make this job easier.. in total you will see a total of 36 ways to fill 1 set of these 3 places, now for the other set of 3 no.s the cases will be 36 because essentially they are the same thing... your answer will be 36x36=1296, Hope this helps.
