I need the Previous years question papers of class 12th CBSE of Maths, can you provide me the same??? As you want I am here providing you sample paper of the class 12th CBSE of Mathematics. Sample questions: The sides of an equilateral triangle are increasing at the rate of 2 cm/sec. Find the rate at which the area increases, when the side is 10 cm. A class has 15 students whose ages are 14, 17, 15, 14, 21, 17, 19, 20, 16, 18, 20, 17, 16, 19 and 20 years. One student is selected in such a manner that each has the same chance of being chosen and the age X of the selected student is recorded. What is the probability distribution of the random variable X ? Find the mean of X. An urn contains 4 balls. Two balls are drawn at random from the urn (without replacement) and are found to be white. What is the probability that all the four balls in the urn are white ? OR In a game, a man wins rupees five for a six and loses rupee one for any other number, when a fair die is thrown. The man decided to throw a die thrice but to quit as and when he gets a six. Find the expected value of the amount he wins/loses. Here is the attachment of sample paper of class 12th CBSE of Maths. Last edited by Aakashd; June 26th, 2019 at 12:08 PM. |

Re: Previous years question papers of class 12th CBSE of Maths
As you need the Previous years question papers of class 12th CBSE of Maths, here I am uploading a PDF file that contains the same. This attachment contains both objective and descriptive types of the questions. Following questions has been taken from the attachment: A manufacturer produces nuts and bolts. It takes 1 hour of work on machine A and 3 hours on machine B to produce a package of nuts. It takes 3 hours on machine A and 1 hour on machine B to produce a package of bolts. He earns a profit of 3 17.50 per package on nuts and 7 7 per package of bolts. How many packages of each should be produced each day so as to maximize his profits if he operates his machines for at the most 12 hours a day ? Form the above as a linear programming problem and solve it graphically. Prove that J (Kx + G x ) d x = .5 0 Evaluate ((2x2 + 5x)dx as a limit of a sum. Using the method of integration, find the area of the region bounded by the lines 3x-2y+ 1 =0,2~+3y-21=Oandx-5y+9=0. 28. ~ % ~ ~ ~ - d i z &m*m*miS. I Show that the height of a closed right circular cylinder of given surface and maximum volume, is equal to the diameter of its base. Rests of the questions are in the attachment, please click on it….. |
