5. Set N consists of all natural. Number from 1 to 10. There numbers are selected at random from this set. Find the probability that the product of two of the number is equal to the third.

(A)

(B)

(C)

(D)

Answer: D

Solution:

The only set of number possible = (2,3, 6) (2,4, 8) and (2,5, 10) thus required probability

7. A rectangle with perimeter 88 m is partitioned into 5 congruent rectangles as shown in the diagram. The Perimeter of each of the congruent rectangle is

A Rectangle with Perimeter 88 M is Partitioned into 5 Congru …

(A) 80

(B) 40

(C) 120

(D) None of these

Solution:

A Rectangle with Perimeter 88 M is Partitioned into 5 Congru …

Here AD = BC , 3a = 2b, a = 2y, b = 3y

The Perimeter of rectangle

The Perimeter of each of the congruent rectangle is

8. The integers 34041 and 32506, when divided by a three digit integer n, leave the same remainder. What is the value of n?

(A) 289

(B) 367

(C) 453

(D) 307

Answer: D

Solution:

If 34041 and 32506 are the only two terms in an AP, they will have common difference of 32506 - 34041 = 1535. Thus, all numbers which are factors of this common difference will divide the integers such that they will leave a constant remainder.

Now go from answer option. We are looking for factors of 1535. Of the answer options, only 307 is a factor of 1535.

9. A square field has length of 4 meter. On the one corner of the square, a cow is tied with the rope length of 5 meter. What is the maximum area cow can graze? (Approximate)

(A) 17

(B) 12

(C) 15

(D) 18

Answer: (C)

Solution:

On the One Corner of the Square

Area of square – area of triangle

Area grazed by cow should lie around 15.

10. what is the value of S?

(A) 2020

(B) 5050

(C) 5024

(D) 5000

Answer: B

Even simple ways of calculation would be.

= sum of first 100 natural numbers

11. The function f (x) satisfies the equation , for all x not equal to Zero. The value of (99) is

(A) 0

(B)

(C)

(D) 1

Answer: C

Substituting gives and substituting

98 times of first equation plus 99 times of the second equation simplify to 9703 f (99) = 197.
