An article sold at a profit of 20% if both the cost price and selling price would be Rs.20/- the profit
would be 10% more. What is the cost price of that article?

• I think question should be if both cost price and selling price would be Rs.20 less.
  let c.p-x and s.p-1.2x
  1.2x-20 = 1.3(x-20)
  x = 60

• In a chemical plant, there are 5 pipelines A, B, C, D and E carrying pure water, 10% HCL, 20% HCL, 30% HCL and 40% HCL respectively. A, B, C, D and E can individually fill a cistern in 20, 30, 60, 90 and 120 hours respectively. On Monday morning at 10 am pipe A is opened. Thereafter at the end of every hour, the other pipes are opened in the order B, C, D and E. The concentration of HCL in the cistern at 6 pm on the same day will be?
  A)7%
  B)8.9%
  c)9.8%
  D)10.78%

• actual cost price = Rs 60 and selling price with 20% profit = Rs. 72.
  If CP and sp is Rs 20 less, then
  cp=Rs 40 and Sp = Rs 52 and hence profit is 30%.
  
  so cp = Rs 60.
