A magazine charges Rs 300 per 10sqcm area for advertising. A company decided to order a half page advertisement. If each page of the magazine is 15cm × 24cm, what amount will the company has to pay for it?


Charges of 10 sq.cm of advertisement = Rs 300


Charges for 1 sq.cm = 300 / 10


= Rs 30


Area of 1 page of magazine = 15 × 24


= 360 sq.cm


Area of half page = 360 / 2


= 180 sq.cm


So Charges for half page advertisement = 180 × 30


= Rs 5400
