1.1 (Question:251316.0)

from where did 1.1 and .85 come

Question:

 A person sold a table at 10% profit and chair at 15% loss. If in this deal there is no profit no loss then find the ratio of the cost price of table and the cost price of chair.

 

Options:
A)

 3 : 2

B)

 2 : 3

C)

 18 : 17

D)

 17 : 18

Solution:

    Let CP of a table = x

    CP of chair = y

    total CP of table and chair = total s.p. of table and chair

  x+y=1.1x+0.85y   

  ·15y=·1x   

  xy=1.51=32   

    CP of table : CP of chair = 3 : 2

10 % profit = 110/100 Cp1 ==> 1.1 and 15 % loss = 85/100 Cp2 ==>0.85.
