If A = 315 then find the value of 3(tan2⁡ A + cot⁡A − 3)2?

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 1
Given: Angle A = 315°

⇒ 3 (tan2A + cot A – 3)2 = 3 (tan2(315°) + cot (315°) – 3)2

⇒ 3(tan2(315°) + cot (315°) – 3)2 = 3(tan2(360° - 45°) + cot (360° - 45°) – 3)2

We know that, tan (360° - θ) = - tan θ and cot (360° - θ) = - cot θ then,

⇒ 3(tan2(315°) + cot (315°) – 3)2 = 3(tan2 45° - cot 45° - 3)2

As we know that, tan 45° = 1 = cot 45°,

⇒ 3(tan2⁡ A + cot⁡A − 3)2 = 3 (9) = 27

If X={4n − 3n − 1, n ∈ N} and Y = {9n − 9, n ∈ N}, then X ∪ Y is equal to:

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 7
Concept

Set theory:

A ∪ B means set of all the values in the set A and B.

A ∩ B is the set of common elements of A and B.

Binomial theorm:

(a+b)n = nC0anb0 + nC1an − 1b1 + nC2an − 2b2 +…+ nCn − 2a2bn − 2 + nCn−1a1bn−1 + nCna0bn

Calculation:

Given X = {4n − 3n−1, n ∈ N} and Y = {9n−9, n ∈ N}

x = 4n − 3n−1 = (3 + 1)n − 3n−1

(∵ nCn−1 = n and nCn = 1)

⇒ X = 32(nC03n−2+nC13n−3+nC23n−4+…+nCn−2)

⇒ x = 9(nC03n−2+nC13n−3+nC23n−4+…+nCn−2)

For n ≥ 2, X is some multiple of 9.

And Xn = 1 = 0

∴ X = {0, some multiples of 9 but not all} .....(i)

Y = 9n − 9 = 9(n − 1)

∴ Y = { All multiple of 9 starting from 0} .......(ii)

From (i) and (ii) we can say,

∴ X ∪ Y = Y

Hence, the correct option is (A).

IPMAT Mock Test - 9 (New Pattern) - Question 8

If the sum of n numbers in the GP 4, 8, 16,… is 2044 then n is?

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 8
Given series is 4, 8, 16,…

Here, a = 4, r = 2

Sum of n numbers = Sn = 2044

As we know that, Sum of n terms of GP

= Sn = a(rn − 1)/r − 1

Where r > 1

∴Sn = 4(2n − 1)/2 − 1

2044 = 4×(2n − 1)

⇒ 511 = (2n − 1)

⇒ 2n = 512

⇒ 2n = 29

∴ n = 9

Hence, the correct option is (D).

IPMAT Mock Test - 9 (New Pattern) - Question 9

In a factory, the average salary of the employees is Rs. 1500. After the inclusion of 5 employees, the total salary increased by Rs. 3000 and the average salary was reduced by Rs. 100, then now the number of employees are:

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 9
Given

Average salary of all employees = Rs. 1500

Total salary increased by Rs. (3000 after 5 new employees

Decrease in average after new employees induction = Rs. 100

Formula used:

Average of n numbers = sum of total numbers/n

Let the total number of employees before new employees induction = x

⇒ Total salary of the employees = 1500x

⇒ After new induction, total salary = 1500x + 3000

Then, according to the question:

1400 = ((1500x + 3000)/x) + 5

⇒ 1400x + 7000 = 1500x + 3000

⇒ x = 40

⇒ x + 5 = 45

∴ Now the number of employees = 45

Hence, the correct option is (D).

IPMAT Mock Test - 9 (New Pattern) - Question 10

The average age of 3 sisters is 15. If the ages of 2 sisters are 12 years and 15 years, the age of the third sister is:

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 10
Let the ages of sisters be x, y, z.

So,

(x + y + z/3) = 15

x + y + z = 45

Given that x, y = 12, 15

⇒ 12 + 15 + z = 45

⇒ z = 18

Therefore, age of third sister is 18 years.

Hence, the correct option is (C).

IPMAT Mock Test - 9 (New Pattern) - Question 11

On selling an article for Rs. 265 a man loses 4%. In order to gain 12%, for how much he must sell the article?

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 11
Gain % = ((SP − CP)/CP) × 100

Loss % = ((CP − SP)/CP) × 100

Let the Cost price of article be x

Loss =4%

Selling price of article = x − (4/100) × x = 0.96x

0.96x = 265 ⇒ x = Rs. 276

Now the article is sold at gain

Gain = 12%

Selling price of article = 276 + (12/100) × 276 = Rs. 308

Hence, the correct option is (B).

IPMAT Mock Test - 9 (New Pattern) - Question 12

The divisor is 25 times the quotient and 5 times the remainder. If the quotient is 16, the dividend is:

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 12
From given data-

Quotient is 16 and the divisor is 25 times the quotient.

⇒ Divisor = 25 × 16 = 400

Also, divisor is 5 times the remainder

⇒ Remainder = divisor/ 5

= 400/5 = 80

We know that,

Dividend = quotient × divisor + remainder

⇒ Dividend = 16 × 400 + 80

= 6480

Hence, the correct option is (B).

IPMAT Mock Test - 9 (New Pattern) - Question 13

In a two digit number, the digit at the unit's place is 1 less than twice the digit at the ten's place. If the digits at unit's and ten's place are interchanged, the difference between the new and the original number is less than the original number by 20. The original number is:

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 13
Let the ten's digits be x.

Then,Unit digit be 2x - 1

Original number:

= 10x + 2x - 1

= 12x - 1

New number:

= 10(2x - 1) + x

= 20x - 10 + x

= 21x - 10

According to the question,

(21x - 10) - (12x - 1)

= (12x - 1) - 20

9x - 9 = 12x - 21

3x = 12

x = 4

Original number:

= 12x - 1

= 12 × 4 - 1

= 47

Hence, the correct option is (D).

IPMAT Mock Test - 9 (New Pattern) - Question 14

If 432P1 is completely divisible by 9, then what is the value of P?

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 14
We know that if the sum of digits in a number is divisible by 9 then the number is divisible by 9.

Now 4 + 3 + 2 + P + 1 should be divisible by 9.

So, 10 + P should be divisible by 9.

Also P is a single-digit number.

The number after 10 which is divisible by 9 is 18.

So P = 18 − 10 = 8

Hence, the correct option is (B).

IPMAT Mock Test - 9 (New Pattern) - Question 18

Shikha invested a total of Rs. 1500 in two different schemes offering simple interest of 6% and 4% respectively. In two years' time, the scheme offering higher interest rate gives Rs. 100 more interest than the scheme offering the lower rate. What was the ratio of amount invested at higher interest rate to the other amount?

Detailed Solution for IPMAT Mock Test - 9 (New Pattern) - Question 18
Let the sum invested by Shikha in the Scheme offering a higher interest rate be x.

So, Sum invested by Shikha in another scheme = (1500 - x)

Thus,

= 100

= 100

On solving,

x = Rs. 1100

Another amount = 1500 − 1100

= Rs. 400

Thus, the required ratio = 11 : 4

Hence, the correct option is (B).

2y + 3x − 8 = 0 ..(ii)

Subtracting 2× (i) from (ii)

−x + 2 = 0

x = 2

Putting back in (i):

y + 2 × 2 − 5 = 0

y = 1

So center is (2,1) and radius is 4.

The equation of circle:

(x − 2)2 + (y − 1)2 = 42

x2 + 4 − 4x + y2 + 1 − 2y = 16

x2 + y2 − 4x − 2y − 11 = 0

Hence, the correct option is (B).
