Question 51
A magazine charges ₹ 300 per 10 sq cm area for advertising. A company decided to order a half page advertisement. If each page of the magazine is 15 cm×27 cm, what amount will the company has to pay for it?
Given, charges for 10 sq cm advertisement = ₹ 300
∴ Charges for 1 sq cm advertisement = ₹ 30010 sq cm×1 sq cm = ₹ 30
In order to find out the amount the company has to pay for a half page advertisement, we will find the area of half page of magazine and then multiply it with the charges for 1 sq cm advertisement.
Now, area of 1 page of magazine = 15 cm×24 cm = 360 cm2
∴ Area of a half page of magazine =Area of 1 page of magazine2
= 3602=180cm2
So, charges for half page advertisement
= Area of half page of magazine× Charges for 1 sq cm advertisement
= 180 ×30
= ₹ 5400
Hence, the company has to pay ₹5400 for it.
