prabhat ordered 4 arrow shirts and some additional park avenue shirts. the price of 1 arrow shirt was twice that of 1 park avenue shirt. when the order was executed it was found that the number of the two brands had been interchanged. the increased the bill by 50%. the ratio of the number of arrow shirts to the number of park avenue shirts in the origial was???

1) 1:3
2) 1:4
3) 1:2
4) 1:5

• Given Number of arrow shirt =4
  Assume Number of Park Avenue = P
  Given Price of one arrow shirt = 2* Price of one Park Avenue shirt..
  Let,Price of one Park Avenue shirt = x
  => Price of one Arrow Shirt = 2*x
  Total Price = 4*2*x+ P*x
  But question says two had been interchanged
  => Number of Arrow Shirt is P and number of Park Avenue shirt is 4
  Total Price = 2*P*x + 4*x
  From question
  New total is 140% of old total
  140/100*(8*x + P*x) = (2*P*x + 4*x)
  Solving this gives x = 12
  => 4:12=> 1:3

  if x is no of shirts of park avenue and y is price of shirt of park avenue, then
  (8y+xy)*3/2 = 4y+2xy
  x=16
  ratio of the number of arrow shirts to the number of park avenue shirts in the origial = 4:16 or 1:4
