The relation 'has the same father as' over the set of children is:

Detailed Solution for IPMAT Mock Test - 3 (New Pattern) - Question 22
For a, b in the set of children, we say that a and b are related if a has the same father as b.

Now, we will check for each property one by one.

The relation is obviously reflexive as a has the same father as a.

Therefore, aRa .... (1)

If a has the same father as b, then that means both a and b have the same father.

Therefore, b also has the same father as a. Thus, the relation is symmetric.

Therefore, aRb implies bRa .... (2)

Now, assume that aRb and bRc.

That means a has the same father as b and b has the same father as c. This implies that a, b and c have the same father.

Therefore, a has the same father as c. Thus, the relation is transitive.

Therefore, aRb, bRc implies aRc .... (3)

Thus, from (1), (2) and (3), we conclude that the given relation is an equivalence relation.

Hence, the correct option is (D).

⇒ 8x = 3

⇒ x = 3 / 8

Hence, the correct option is (A).

IPMAT Mock Test - 3 (New Pattern) - Question 24

In a group of 70 people, 37 like coffee, 52 like tea and each person likes at least one of the two drinks. How many people like both coffee and tea?

Detailed Solution for IPMAT Mock Test - 3 (New Pattern) - Question 24
Let C denote the set of people who like coffee, and T denote the set of people who like tea.

It is given that in a group of 70 people, 37 like coffee, 52 like tea and each person likes at least one of the two drinks.

Therefore,

n (C) = 37, n (T) = 52 and n (C υ T) = 70.

We know that n(C υ T) is given by,

n (C υ T) = n (C) + n (T) - n (C ∩ T)

From this,

n (C ∩ T) = n (C) + n (T ) - n (C υ T)

= 37 + 52 - 70

= 89 - 70

= 19

Therefore, 19 people like both coffee and tea.

Hence, the correct option is (A).

IPMAT Mock Test - 3 (New Pattern) - Question 25

What is the number of different messages that can be represented by three a’s and two b’s?

So, on with n = n1 + n2 + n3 +…+ nk then the number of distinguishable permutations of the n objects is:

=

Given: Three a’s and two b’s

Total number = 3 + 2=5

In the set of 5 words has 3 words of one kind and 2 words of the second kind.

Therefore, number of different messages that can be represented by three a's and two b's,

= 5! / 3!2! = 10

Hence, the correct option is (D).

IPMAT Mock Test - 3 (New Pattern) - Question 26

Let L denote the set of all straight lines in a plane. Let a relation R be defined by lRm if and only if l is parallel to m,∀ l, m ∈ L. Then R is:

Detailed Solution for IPMAT Mock Test - 3 (New Pattern) - Question 26
Let's check the given relation for its type one by one.

Reflexive: Every line is parallel to itself. It means that lRl for all l∈L. Therefore, R is reflexive.

Symmetric: If a line l is parallel to m, then m is parallel to l, i.e., if lRm ⇒ mRl, ∀ l ,m∈L. Therefore, R is symmetric.

Transitive: If a line l is parallel to m and m is parallel to k, then l is also parallel to k, i.e., if lRm and mRk ⇒ lRk,∀ l, m, k ∈ L. Therefore, R is transitive.

Since, the relation R is reflexive, symmetric and transitive as well, it is an equivalence relation.

Hence, the correct option is (D).

We know that,

Discount = MRP- Selling Price

According to the question,

Discount =80,000 − 60,000

= Rs. 20,000

Therefore, the rate of discount will be,

Discount % = Discount / MRP × 100

= 20,000 / 80,000 × 100

= 25%

Hence, the correct option is (D).

IPMAT Mock Test - 3 (New Pattern) - Question 28

The average of 12 numbers is 14. If each number is doubled, then what will be the new average?

Detailed Solution for IPMAT Mock Test - 3 (New Pattern) - Question 28

Average =sum of number / total numbers

⇒14 = sum of 12 numbers / 12

⇒ sum of 12 numbers = 14 × 12 = 168

Let the numbers be a1, a2, a3……a12

⇒ a1 + a2 + a3 +……+ a12 = 168

If each number is doubled,

Numbers will be, 2a1, 2a2, 2a3……2a12

⇒ 2a1 + 2a2 + 2a3 +…. + 2a12

⇒ 2(a1 + a2 + a3 +…+ a12)

⇒ 2 × 168 = 336

New average = sum of numbers / total numbers = 336 / 12 = 28

Hence, the correct option is (A).

IPMAT Mock Test - 3 (New Pattern) - Question 29

With a uniform speed, a car covers a distance in 8 hours. Had the speed been increased by 4 km/hr, the same distance could have been covered in 7 hours and 30 minutes. What is the distance covered?

Detailed Solution for IPMAT Mock Test - 3 (New Pattern) - Question 29
Let the distance be x km.

As we know,

The speed of the car = x / 8

7 hours 30 minutes = 7 + 1 / 2 hours

= 15 / 2 hours

If the speed was increased by 4 km/h, then the speed of the car = x / 15 / 2

According to the question,

x /15 / 2 − x / 8 = 4

⇒16x − 15 x /120 = 4

⇒ x = 480 km

Hence, the correct option is (B).
