Question
The marked price of a pen and pencil is in the ratio of
5:6. The shopkeeper gives a 10% discount on the pen. If the total discount on both the pen and the pencil is 10%, then the discount offered on the pencil is?Solution
The ratio of the marked price of the pen and pencil=5:6 So let the mark price of pen =500 Rs. and pencil =600 Rs. 10% discount on the pen =500×10/100=50Rs. 15% discount on (pen + pencil) =500+600=1100×10/100 =110Rs. Now discount on pencil =110-50=60 Discount % on the pencil = (60/600) ×100 =10%
