Question

a border of 3 cm width is printed on 500 sheets of paper each of length 40 cm and with 30 cm if it costs 50 paise to print 100cm square of border find the total cost of printing the border​

Answer 1

Answer:

₹960

Step-by-step explanation:

Total number of sheets = 500

length = 40cm    breadth = 30cm     border = 3cm

Area of border on one paper

= (2 x 30 x 3) + (2 x 34 x 3)

= 180 + 204

= 384$cm^2$

Area of border for 500 sheets of paper

= 500 x 384

= 192000$cm^2$

Cost printing border is 50 paise per 100$cm^2$

∴ cost is ₹1 per 200$cm^2$

So, Total cost = $\frac{192000}{200}$ = ₹960
