x is divisible by 140 .1) x is divisible 5 and 2 2) x is divisible by 7 and 2

• na re navneet g kha gye na galthi beta yr elitmus hai jo simple lagtha hai na uska answer kuch aur he hota hai ,,take example of 490/140 ,,490 is divisible by 7,2,5 but still not divisble by 140 ,,both are not sufficient ..

• Question was:
  Is x divisible by 140?
  The answer will be YES or NO.
  So it can be answered by either of the statement alone.

• Both the statements cannot decide whether x is divisible by 140 or not.
  There is a series of such numbers which is divisible by 2,5,7 but not by 140
  
  First number is 140+70=210(divisible by 2,5,7 but not by 140)
  Now keep on adding 140 to get the series
  210+140 = 350(divisible by 2,5,7 but not by 140)
  350+140 = 490(divisible by 2,5,7 but not by 140)
  .....
  .....
  so on....

• plz post the qstn correctly......it's not understandable....

• x is divisible by 5 & 2
  Also x is divisible by 7 & 2
  => x is divisible by Lcm of 5,2,7,2 = 5*2*7 = 70 but doesn't guarentee divisibility by 140 ...
  =>ans is both statements r nt sufficient.

• First of all I think the question is about data sufficiency, And the answer should be that both the statements together are not sufficient as 140 has 7,2 and 5 as prime factors. So, to check the divisiblity by 140 no. should be div by 5,2 and 7.
• 11 years agoHelpfull: Yes(2) No(1)
• 140 has prime factors 2,5,7 so these must be present in chosen number thus 1.0 and 2.) both are required for divisibility of x by 140

• aadarsh but here it is alreday givn tht x is devided by 140...if it is devided by 140...so x wll be..140 ,280,420...soon n thse wll be devided bt..2 ,5,7 and 140 also.........so it sld be yes..am i right?..

• @ shiladitya waise kuch bhi nhi iska answer both are not sufficient ..kya keh rhi ho yr tum khul ke explain karo ?
• 11 years agoHelpfull: Yes(0) No(1)
• The question asked yes or no . so from statement 1 and 2 both give the ans NO so the correct option was B
• 11 years agoHelpfull: Yes(0) No(1)
• either of the can give the ans
  22*5=110
  140
  now
  14*11=11*14,calculate one of the above
  11*14+1540
  so it is divisible by both the statement
