  Three numbers A,B,Care in ratio 1:2:3. Their average is 600. If A is increased by
  10% and B is increased by 20%, then to get the average increased by 5%, C will increased by:
  a)90
  b)100
  c)150
  d)180
  ans
  Let be A= x, B=2x, and C=3x.
  (x+2x+3x)/3=600
  this will be x=300
  so, the numbers will be 300,600,900
  new average= 105%of 600= 630
  Let 110% of 300+80% of 600 + y= 630*3
  solve it for y, you will get, y=1080
  so, increase in C= 1080‐900 =180 ans
  
  
  
  =========================
  A and B together can complete a work in 12 days. A alone can complete it in 20 days.
  If B does the work only for half a day daily, then in how many days A and B together
  will complete the work?
  A. 10 days B. 11 days
  C. 15 days D. 20 days
  ans
  see ,
  here given that A and B can do the work in 12 days
  so A+B 1 day work = 1/12 unit.................................(1)
  also given that , a alone can finish the work in 20 days
  therefore
  A 1 day work = 1/20 unit........................................(2)
  using 1 and 2
  we get,
  B's 1 day work =1/12 ‐ 1/20
  =1/30..............................(3)
  ‐‐‐> b can do the complete work in 30 days
  now according to statement
  if b does the work only half a day then it takes double days (i.e. 60) to complete the work
  so now B 1 day work = 1/60.
  also we know
  A 1 day work = 1/20
  now,
  A+B 1 day work = 1/60 + 1/20
  = 4/60
  = 1/15 unit work
  hence ,
  A and B together will complete the work in " 15 DAYS " (answer)
  10 women can complete a work in 7 days and 10 children take 14 days to complete the

  C. 5 D. 7
  ans
  5 women's 1 day work=1/14
  ans= 1/14 + 1/14
  = 1/7 units of work
  so 7 days
  ===============================
