Students can check out the memory based ISC Class 12th Maths 2024 question paper and answer key given below.

Section C

Q1. A company sells hand towels at ₹100 per unit. The fixed cost for the company to manufacture hand towels is ₹35,000 and variable cost is estimated to be 30% of total revenue. What will be the total cost function for manufacturing hand towels?

1. 35000+ 3x
2. 35000+30x
3. 35000+100x
4. 35000+10x

Ans. B) 35000+30x

Q2. If the correlation coefficient of two sets of variables (X, Y) is, which one of the following statements is true for the same set of variables?

1. Only one of the two regression lines has a negative coefficient.
2. Both regression coefficients are positive.
3. Both regression coefficients are negative.
4. One of the lines of regression is parallel to the x-axis.

Ans. C) Both regression coefficients are negative.

Q3. If the total cost function is given by C = x + 2x²-2x², find the Marginal Average Cost function (MAC).

Ans.

MAC = 4x-7/2x

Q4. The equations of two lines of regression are 4x+3y+7=0 and 3x+4y+80. Find the mean value of x and y.

Ans. 

x= -4/7, y= -11/7

Q5. The manufacturer of a pen fixes its selling price at 245, and the cost function is C(x)=30x+240 The manufacturer will begin to earn profit if he sells more than 16 pens. Why? Give one reason.

Ans.

45n=30n+240 

15n=240 

n=16

If 16 pens are sold, the revenue will just cover the total cost (C(x) = R(x) = 30(16) + 240 = 480). Therefore, there will be zero profit. The manufacturer must sell more than 16 pens to generate revenue exceeding the total cost and gain profit.
