The percentage expenses on various items during book production and sale.

(a) The cental angle for the sector on “Paper-Cost” is :

[A]22.5°

[B]36°

[C]16°

[D]54.8°

**36°**

100%=360°

∴1%=360°/100

∴10%=360°*10/100=36°

(b) If the ‘Printing -Cost’ is 17500 RS. The royalty paid is :

[A]6300 Rs.

[B]7500 Rs.

[C]8750 Rs.

[D]3150 Rs.

**7500 Rs.**

35% total cost = Rs. 17500

∴15% of total cost =

(c) If the “miscellaneous expenses” are Rs. 6000. How much more are “binding and cutting charges” than “Royalty”?

[A]Rs. 10500

[B]Rs. 4500

[C]Rs. 6000

[D]Rs. 5500

**Rs. 4500**

Difference in per cent cost of ‘binding and cutting charges’ and ‘rotalty’ = (18-15)%= 3%

Now, 4% of total cost = Rs. 6000

∴ 3% of total cost =

(d) The central angle corresponding to the sector on “Printing Cost” is more than that of “Acvertisement Charges” by:

[A]54.8°

[B]61.2°

[C]72°

[D]60°

**61.2°**

Difference in per cent expensses on printing cost and advertisement charges = (35 – 18)% = 17%

Now, 1% = 3.6%

∴ 17% = 3.6°17=61.2°

(e) The “Paper Cost” is approximately what percent of “Printing Cost”?

[A]32.5%

[B]30%

[C]20.3%

[D]28.6%

**28.6%**

The required per cent = = 28.6% (approx)
