उत्तर
Given, charges for 10 sq cm advertisement = ₹ 300
∴ Charges for 1 sq cm advertisement = `(₹ 300)/(10 "sq cm") xx 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 magazine")/2`
= `360/2`
= 180 cm2
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.
