P works faster than q. Will he take more than 20 days to complete a job X ?1) The sum of times that p and q would take to complete X is 50 days2) p would take 10 days less than q to complete xopitons:a)If the data in St1 alone is sufficient while data in st2 alone is notb)data in st2 alone is suffice , while data in st1 alone is notc)if the data in st1 alone or st2 alone but not bothd)if the data in both the st's together is suffice to answer the questione)if the data even in both the st's together is not suffice to answer the question
@krum I agree.." but from st1 p and q takes 50 days.. then by any means.. p will take more than 50 days to complete tht work.. assuming b doesnt do a negative work.. " am i flawed in the quoted lines any wer ?

No it does'nt say like that !! the no. of days taken by p + no. of days taken by q = 50 days !! thats what it says !!
@bullseyes@krumMy take is also a) but TIME says its d).. Krum pls explain..
It will be d.
St1: p+q =50 and p is faster than q. u can have 24+26 OR 19 + 31. In both the cases P is faster but >20 in first case and combine St2 and ull get the answer. Hence D

@kingsleyx converting his words to expression...1/P + 1/Q = 1/50 => P,Q>=50 ??
does my expression is wrong ?
@krum @Ibanez @kingsleyx @bullseyes by common sense also. if both took 50 days, den individually each will definitely take more than 50 days to complete tht work...

"The sum of times that p and q would take to complete X is 50 days" is different from "the time taken by them working together " !! If its the second, then ur equation is absolutely right but I guess it means the first here. correct me if I am wrong !

That expression is wrong. Question does not state that they together take 50 days to complete the work. It states that the number of days taken by P + number of days taken by Q = 50.Interpret it like that
pls share the approach for this question guys..what is the product of 6843256709 and 125 ?855407088625855407087625855400788625855407088525855407089625
the digit sum comes out to be 4.. only a & d satisfy this. now last 3 digit of both are 625 and 525. think a lil abt divisibility of 125 and u get ur answer as "a"
