List of few questions of XII CBSE Mathematics is given below:
There is a group of 50 people who are patriotic out of which 20 believe in non violence. Two persons are selected at random out of them, write the probability distribution for the selected persons who are non violent. Also find the mean of the distribution. Explain the importance of Non violence in patriotism.

Find the area of the region enclosed between the two circles x2+y2=1 and
(x-1)2 + y2 = 1

Find the particular solution of the differential equation:
(x-sin y)dy + (tany)dx = 0 : given that y=0 when x=0

A dealer in rural area wishes to purchase a number of sewing machines. He has only Rs. 5760.00 to invest and has space for at most 20 items. A electronic sewing machine costs him Rs.360.00 and a manually operated sewing machine Rs. 240.00.He can sell an Electronic Sewing Machine at a profit of Rs. 22.00 and a manually operated sewing machine at a profit of Rs.18.00. Assuming that he can sell all the items that he can buy how should he invest his money in order to maximize his profit. Make it as a linear programming problem and solve it graphically. Keeping the rural background in mind justify the ‘values’ to be promoted for the selection of the manually operated machine.

Two schools A and B decided to award prizes to their students for three values
honesty (x), punctuality (y) and obedience (z). School A decided to award a total
of Rs. 11000 for the three values to 5, 4 and 3 students respectively while school B
decided to award Rs. 10700 for the three values to 4, 3 and 5 students respectively.
If all the three prizes together amount to Rs. 2700, then.
i. Represent the above situation by a matrix equation and form Linear
equations using matrix multiplication.
ii. Is it possible to solve the system of equations so obtained using
matrices?
iii. Which value you prefer to be rewarded most and why?
