Class 12th

As we do not know that what part of the market share of C2, C3, C5 has been eaten by C5& in what proportion. So, we cannot find the answer.

Total Market in 2024 = 1.1 * 1.1 * 11520 = 14000 (approx.)

New Market = 14000 – 2480 = 1240. As C4 captures $\frac{1}{3}$ of 2480; so the approximately share of C4 in 2024 = 28% of (11520) + $\frac{1}{3}$  * 2480 = 4050

So, percentage share of C4 in 2024 = $\frac{4050}{14000}*100=29\mathrm{\%}(approx.)$

11520 = 8000 (1+r)²

R=20 percent

Sales of C5 in 2020 = 20 % of 8000 = 1600 cr.,

Sales of C5 in 2022 = 20% of 11520 = 2340 cr.

So, percentage increase = $\frac{2304-1600}{1600}*100=44\mathrm{\%}$

The per capita production of Nutralite Butter was the most in 2013. (by observation)

Let the total cost is 100, then Marketing cost = 30, New Marketing cost after the increase of 20% = 1.2 (30) = 36, New Total cost = 106. So, the percentage shown of Marketing cost.

Let the total cost is 100, then Publishing cost = 35% of 100 = 35 & Marketing Cost = 30 % of 100 = 30. So, by  the Publishing cost is 16.66% more than the Marketing cost.

Let the total cost of writing the book is x.

So, 12 % of x =14400, Cost of Others = 15% of Total cost = 15 % of 1,20,000 = 18,000.

Shown of Printing is 8 % of the total cost. Here 100% = 360°. So, 1% = 3.6°.

So, central angle = 8 * 3.6 = 28.8°

Verify the choices one by one.

(a) The total sales of all the four companies was different in each month, hence (a) is false.

(b) For the given period:

Total Sales of C1 = 175 +150 + 225 + 250 + 150 + 200 = 1150.

Total Sales of C3 = 75 + 75 + 100 + 100 + 50 + 75 = 475.

Hence, (b) is false.

(c) Total Sales of C2 for the given period = 650

Required percentage

$=\frac{650}{1150+475+1375+650}=17.8\mathrm{\%}$

(d)          The sales of C2 were less than the sales of C4 in each month. Hence, (d) is false
