Some questions from the Class 12 Maths Question Paper are given below:

Question:

If a*b denotes the larger ‘a’ and ‘b’ and if a o b = (a * b) + 3, then write the value of (5) o 10, where * and o are binary operations.

Solution:

Given:  ab = (a * b) + 3

Here a * b denotes the larger of 'a' and 'b'.

Substitute a = 5 and b = 10 in a ∘ b = (a * b) + 3
5 ∘ 10 = (5 * 10) + 3

= 10 + 3    [5 * 10 = 10]

= 13

Question:

Find the magnitude of each of the two vectors a and b, having the same magnitude such that the angle between them is 60o and their scalar product is 9/2.

Solution: Question:

Find the value of:

tan‒1√3 ‒ cot‒1 (‒√3).

Solution: Question:

The total cost C (x) associated with the production of x units of an item is given by C (x) = 0.005 x3‒ 0.02 x2 +30 x + 5000. Find the marginal cost when 3 units are produced, where by marginal cost we mean the instantaneous rate of change of total cost at any level of output.

Solution: Question:
