The cost price of 26 articles is the same as the selling price of x articles. If the profit is 30%, then the value of x is: A) 20 B) 18 C) 25 D) 15

• Let CP of 1 article=100
  profit=30% then
  SP of 1 article=130
  CP*26=SP*x
  100*26=130*x
  2600=130x
  x=20

• c.p of 1 article =1 re
  c.p of x article =x re
  c.p of 26 article =26 re
  given s.p of x articles = 26 re
  profit= (26-x)
  so, (26-x)*100/x=30
  x=20

• c.p of 26 articles=s.p of x articles
  
  c.p/s.p=x/26
  
  profit%=profit/c.p*100
  
  30=(26-x/x )*100
  
  x=20

• %Profit = ((S.P-C.P)/(C.P))------>Profit=((S.P-C.P)/(C.P))*100
  here S.P of x articles = C.P of 26 articles, %profit=30%------>profit=30
  So, 30=((26-x)/(x))*100------->x=20(ANSWER)

• short cut: when CP of x=SP of y then profit/loss = (x-y)/y
  here ATQ, (26-x)/x=30%
  solve for x'
  x=20(ANS)

• 26cp=x*sp here retio of cp& sp is X/26
  In second step we know that because of 30 %gain retio of cp& sp is 100/130
  Both will be equal then uh will get tha ans X= 20
