From 2018 onwards, the National Testing Agency (NTA) will conducted JEE Main exam twice in twice a year in a fully computer based test (CBT) mode. The first phase of the exam will be conducted in the month of January 2019, while the next exam will be conducted in April.

In this article, we are going to provide you solved practice paper of Mathematics which will help you to know the difficulty level of the questions which can be asked in JEE Main Examination 2018. Students should solve lot of practice papers to overcome the fear of exam.

Why should students solve practice papers?

1. To get familiar with the pattern and difficulty level of the exam.

2. To learn new ways of managing speed and accuracy in the examination.

3. To brush up their knowledge.

About the paper:

1. This practice paper contains 30 multiple choice questions with only one correct option.

2. Questions have been taken from different chapters like Relations and Functions, Trigonometric Functions, Complex Numbers and Quadratic Equations, Permutations and Combinations, Binomial Theorem, Sequences and Series, Straight Lines, Limits and Derivatives, Probability, Inverse Trigonometric Functions, Matrices, Determinants, Continuity and Differentiability, Application of Derivatives, Integrals, Application of Integrals, Differential Equations, Vector Algebra, Three Dimensional Geometry.

3. Detail solution for all the questions.

JEE Main Mathematics Syllabus: 2018 – 2019

Few sample questions from the solved practice paper are given below:

Q. The number of odd proper divisors of 2520 is

(a) 12

(b) 10

(c) 11

(d) none of these

Sol. (c)

Here, 2520 = 23 × 32 × 5 × 7

Number of odd proper divisors 

= (2 + 1) (1 + 1) (1 + 1) − 1 = 11


Q. Three dice are thrown at the same time. Find the probability of getting three two’s, if it is known that the sum of the numbers on the dice was six.

(a) 1/10

(b) 3/10

(c) 1/12

(d) None of these.

Sol. (a) 

On a throw of three dice, we have sample space [n(S)] = 63 = 216

Let E1 is the event when the sum of numbers on the dice was six and E2 is the event when three two’s occurs.

⇒ (E1 = {(1, 1, 4), (1, 2, 3), (1, 3, 2), (1, 4, 1), (2, 1, 3) (2, 2, 2), (2, 3, 1), (3, 1, 2), (3, 2, 1), (4, 1, 1)

n(E1) = 10 and E2 ={2, 2, 2}

n(E1) = 1

Q. The number of ways to give 13 different things to three persons A, B, C so that B gets 1 more than A and C gets 2 more than B, is

(d) none of these.


Let A gets x things, then B gets x + 1 and C gets x + 3.

 x + x + 1 + x + 3 = 13

 x = 3

Thus, we have to distribute 13 things to A, B and C in such a way that A gets 3 things, B gets 4 things and C gets 6 things.

Q. The value of sin[2 tan-1(0.75)] is

(a) 0.75      

(b) 1.5 

(c) 0.96      

(d) sin 1.5


Q. The line passing through the extremity A of the major axis and extremity B of the minor axis of the ellipse x2 + 9y2 = 9  meets its auxiliary circle at the point M. Then the area of the triangle with vertices at A, M and the origin O is 

(a) 31/10

(b) 29/10

(c) 21/10

(d) 27/10

Sol. (d)
