Directions: Read the following questions carefully and choose the right answer.
Important for :
1
If the letters of the word PREVIOUS be arranged at random, what is the probability that all the vowels come together?
» Explain it
C
There are total eight letters

∴ n(S) = 8P8 = 8!

As all vowels should come together, we assume them as one letter. Here E, I, O and U together are taken as one, so the number of letters is 4 + 1 = 5 and it can be arranged in 5P5 = 5! ways and the vowels can be arranged in 4! ways among themselves

∴ n(E) = 4! × 5!

 ∴  P(E) = 4!5! = 4 × 3 × 2 = 1 8! 8 × 7 × 6 14

Hence, option (C) is correct.

2
A, B and C start running around a circular field having circumference 150 metre at the same time from the same point. Speeds of A, B and C are 2 m/minute, 2.5 m/minute and 3 m/minute. Find after how much time, they will meet again at the same point for the first time.
» Explain it
D
Time taken by A to complete one round of the circular field

 = 150 = 75 minutes 2

Time taken by B to complete one round of the circular field

 = 150 = 60 minutes 2.5

Time taken by C to complete one round of the circular field

 = 150 = 50 minutes 3

 H.C.F of 75, 60, 50 = 300 minutes = 300 = 5 hours 60

Hence, option D is correct.

3
Aman goes to park daily. His last week average speed with which he completed one round of the park was 47Km/h, for the first four days was 37Km/h, and that for the last four days was 52.5Km/h. Find out the time taken by Aman to travel 203 Km if he travels with the speed of the fourth day.
» Explain it
A
Let, Speed on the fourth day = x

total speed for the first three days = A

& total speed for the last three days = B

Now,

Total speed for the week, S = 47 × 7 = 329

Total speed for the first four days = A + x = 37 × 4 = 148

Total speed for the last four days = B + x = 52.5 × 4 = 210

According to the question,

A + x + B = S

⇒ (A + x) + (B + x) – x = 329

⇒ 148 + 210 – x = 329

⇒ x = 358 – 329

⇒ x = 29Km/h

 Therefore, time taken to travel 203km = 203 = 7 hours 29
Hence, option A is correct.

4
A shopkeeper buys an article from a wholesaler. The shopkeeper marks up the price by 15% on the listed price. A person pays Rs.7590 to get it after paying sales tax at the rate of 10% on the price asked for. If shopkeeper has bought it at a discount of 20% on the listed price, then what is the profit percentage of the shopkeeper?
» Explain it
B
Let the listed price = Rs.100

CP of shopkeeper = 100 – 20 = Rs.80

Marked price by shopkeeper = 100 + 15 = Rs.115

Now,

 115 = 7590 × 100 = 6900 110

 ⇒ 80 = 6900 × 80 = Rs.4800 115

CP of shopkeeper = Rs.4800

Profit = 6900 – 4800 = Rs.2100

 Profit % = 2100 × 100 = 43.75% 4800

Hence, option B is correct.

5
The sum of ages of Rahul and Ravi is equal to sum of the ages of Nitin and Nishant ten years from now. Ravi is older than Nishant by 5 years. The ratio of age of Nitin and Ravi is 3 : 2. If the sum of ages of Rahul and Nitin was 47 five years before, find the age of Rahul at present.
» Explain it
D
Let, age of Nitin = 3x

Thus, age of Ravi = 2x

And age of Nishant = 2x – 5

Let, age of Rahul = a

Now, according to the question,

a – 5 + 3x – 5 = 47

⇒ a = 57 – 3x

Now,

57 – 3x + 2x = 3x + 10 + 2x – 5 + 10

⇒ 6x = 42

⇒ x = 7

Therefore, age of Rahul, a = 57 – 3 × 7 = 57 – 21 = 36 years

Hence, Option D is correct.
