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

Question:

If α is a complex cube root of unity and (1 + α)7 = X + Yω, then X and Y are respectively

equal to

(a) 0, 1

(b) 1, 1

(c) 1, 0

(d) 1, 1

Sol. (d) Question:

Let a die is loaded in such a way that prime number drawn are twice as likely to occur as a

non prime number face. The probability that an odd number will be show up when the die is

tossed is

(a) 1 / 3

(b) 2 / 3

(c) 4 / 9

(d) 5 / 9

Sol. (d) Question:

Three boys and two girls stand in a queue. The probability that the number of boys ahead of every girl is at least one more than the number of girls ahead of her, is

(a) 1/2

(b) 1/3

(c) 2/3

(d) 3/4

Sol. (a)

The number of arrangement of 3 boys and 2 girls is 5!

Let B1, B2, B3 be the boys and G1,G2 be girls

According to given condition, following case may arise

1. G1 G2 B1 B2 B3

2. G1 B1 G2 B2 B3

3. G1 B1 B2 G3 B3

4. B1 G1 G2 B2 B3

5. B1 G1 B2 G2 B3 Question:

The maximum value of the sum of the AP 50, 48, 46,,... is

(a) 620

(b) 550

(c) 520

(d) 650

Sol. (d)

For maximum value of the sum of given sequence to n terms, is when the nth term is either

zero or the smallest positive number of the sequence

i.e.,    50 + (n – 1) (−2) = 0

n = 26 Question:

If the number of ways of selecting n cards out of unlimited number of cards bearing the number 0, 1, 2, so that they cannot be used to write the number 201 is 93, then n is equal to

(a) 2

(b) 3

(c) 4

(d) 5

Sol. (d)

We cannot write 201, if in the selection of n cards, we get either (2 or 1), (2 or 0), ( 0 or 1), (only 0), (only 1) or (only 2) Question:

Find the equation of a curve passing through the point (2, 1), if the tangent drawn at any point P(x, y) on the curve meets the coordinate axes at A and B such that P is the mid-point of AB.

(a) xy = 2

(b) y = x

(c) x = 2

(d) xy = 1

Sol. (a) Conclusion:

After doing a lot of research on previous years’ papers of JEE Main, the subject experts of Mathematics have designed this solved practice paper. Students can also find the detailed solution of each question and save their precious time. It will also help students to track their progress.
