LOD 2 ( progressions) question 33 solution.
1/1 + 1/3 + 1/6 + 1/10 + 1/15 ....
Ans 2) = (2-1)/1 + (3-2)/3 + (4-3)/6 + (5-4)/10 + (6-5)/15 .......
= 2/1 - 1/1 + 3/3 - 2/3 + 4/6 -3/6 + 5/10 -4/10 + 6/15 -5/15 ...
= 2 - 1 + 1 - 2/3 + 2/3 - 1/2 + 1/2 - 2/5 + 2/5
= 2(Ans)

Hey newbie on the rack.. Wanted solution for the famous Three cooks 80 idlis sum of LOD 2 of Arun Sharma Quant book, however while searching through the search bar on the top, it gave me numerous links but all to the previous extinct versions, and none to the current thread. Please let me know the right way if thats not the correct approach to go about looking for answers. Thanks in advance. Of course, the answer to idlis q will be of good help.
A man can climb up a greased pole 30ft high in 15 seconds(where 10 seconds is used for climbing up and 5 seconds when he is slipping down). If grease causes a slip of 2ft per second, the time taken by man to cover up the non-greased pole would be?

Guyzz.. i am a newbie... how to go throught arun sharma with CAT in mind???... i have heard that LOD 2 qstns are closest to the CAT level... could someone give me more insight on hw to use this book to its max?... thanks in advance...😃
Guyz and Galz ! Please help me in solving problems in "Inequalities" by Arun Sharma. Both LOD 1 and LOD 2.As per the explanations given at the end,he has suggested to solve all the problems solely from options(N.B- That's why he hasn't given hints and solutions to all the problems.) .But I think one can't depend on options especially where one of the option is "none of the above".And more to that how to cross check for all the values in a given range in options.Sometimes when I forget to cross check one value in the whole range(after cross checking some values from that range ) and go for that option ,to my surprise I find the answer to be "none of the above" .
