Hi Experts, I approach this problem using Arithmetic Progression to find the number of terms and then take the lcm of 2,3 , 2,5 and 3,5 to get the common terms counted.However,i am not able to get to the result. Can you please let me know if this approach is wrong and if not, how the terms/numbers c...

Your are welcome 
At the point they met,the time duration for which both travelled would be the same as both began to run at the same time.
I hope this helps.

Hi, The question basically asks us how much more distance is Karen running now than would have ,had John not stopped running. Assuming the distance between them to be 100units. John covered 25 units => Karen has to cover 75 units now. In case John ran at his constant speed,At the meeting point Dista...

Hi, I used a rough approach for this question.I approximated the height to be the average of the y-coordinates of(0,3) and (7,4),coming to 3.5. I also approximated the length of this line segment as 7 instead of a more accurate sqrt50. Area = 7X3.5)/2 =24.5/2 apprx=12.5 Probably a little lucky here..

Hi Jose,Both the statements give only the relative pumping rates.Since we need to know how the answer in hours,in my opinion,we cannot determine the same even after combining the statements.
Hence option E(IMO)
Thank you.

Hi Vinay, Statement 1 is not sufficient as the amount he spent or number of articles bought is not given. Statement 2: the average selling price of the article is 0.4*40+0.6*20)/(0.4+0.6)=$28.The cost price was $25 hence the percentage profit is (28-25/25)*100 B sufficient. Kindly correct if wrong.[...

If "x" and "y" are positive integers such that x > y, what is the remainder when x^4 - y^4 is divided by 4? 1. When x-y is divided by 4, the remainder is 0 2. When x+y is divided by 4, the remainder is 1 Hi Vinay! This is how I tried to solve the problem-if you observe,even^4 gi...

Dear Brent/All,
Sorry if this is a silly question-what if the question statement also mentioned that the heights were in Arithmetic progression or progression .Can statement 2 still not be used sufficiently ?It can be,am i correct?
