Question
The marked price of a pen and pencil are in the ratio of
5:6. The shopkeeper gives 20% discount on the pen. If the total discount on both the pen and the pencil is 30%, then the discount offered on the pencil is?Solution
Let the M.P of the pen be 5x. That of the pencils be =6x Discounted price on the pencil =5x ×80/100=4x Total discount price on the pen and pencil =11x ×70/100=7.70x So, the discount price on the pencil=7.70x-4x=3.70x Therefore, % discount price on the pencil=(2.30x/6x) ×100 =38.33%
