Cognizant Aptitude Questions and Answers - Question 1

If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance traveled by him is:

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 1

Let us assume, the actual distance traveled be x km.
Then, x/10 = (x + 20)/14
14x = 10x + 200
4x = 200
x = 50 km.

Cognizant Aptitude Questions and Answers - Question 2

Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 2

The speed of a bus with stoppages  =45 km/hr
The speed of  a bus without stoppages = 54 km/hr
Speed difference = 54 - 45 =  9 km/hr
Therefore, due to stoppages, it covers 9 km less.
By using the above formula,
Time is taken to cover 9 km = (9/54) × 60 = 10 min 
∴ The bus stop is 10 min per hour.

Cognizant Aptitude Questions and Answers - Question 3

The distance between two cities P and Q is 300km. A train starts from station P at 10 am with speed 80 km/hr towards Q. Another train starts from Q towards P with speed 40km/hr at 11 am. At what time do they meet.

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 3

First train starts at 10 am so in one hour it covers 80 km in one hour. Now distance b/w P and Q is 220. Suppose at some’ x’ km they meet. So,
x/80 = (220-x)/40
x = 440/3.
The time after which they meet = (440/3)/80 = 11/6 i.e = 1hr 50 min.
Therefore, they will meet at 12: 50 pm

Cognizant Aptitude Questions and Answers - Question 4

Two cities A and B are at a distance of 60 km from each other. Two persons P and Q start from the First city at a speed of 10km/hr and 5km/hr respectively. P reached the second city B and returns back and meets Q at Y. Find the distance between A and Y.

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 4

Time taken by P to reach city B is 6hr. In 6 hr, distance covered by Q is 30km. Now at some x distance, they will meet. So
x/5 = (30-x)/10. X= 10.
So distance b/w A and Y is 30+10 =40 km
Therefore, the distance between A and Y is 40 km.

The CP of Desk is Rs.2000. A Salesman wants to make 15% profit by selling it. At the time of sale, he declares a discount of 10% on MP. The Marked price is?

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 5

90x/100 = 2000*(115/100)

Therefore, the market price is Rs. 2556.

A boy bought 2 items for Rs.7500. One item he sells at a profit of 16% and another item at 14% loss. In this, the boy makes neither any profit nor any loss. What is the difference between the SP of 2 items?

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 6

116X/100 + (7500-x)86/100 = 7500
116x-86x-645000 = 750000
X = 3500, 7500 – 3500 = 4000
(3500*116)/100 – (4000*86)/100 = 620

A Shopkeeper bought 30 kg of rice at the rate of Rs. 40 per kg. He sold 40% of the total quantity at the rate of Rs. 50 per kg. At what price per kg should he sell the remaining quantity to make a 25% overall profit?

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 7

Total CP of Rice = 30 * 40 = 1200
40% of Total Quantity = 40% of 30 = 12
SP = 12*50 = 600
SP = 1200 * 125/100 = 1500
SP of Remaining Quantity = 1500 – 600 = 900
Remaining Quantity = 18kg
Rice per Kg = 900/18 = Rs. 50

A man borrows Rs 4000 at 8% compound interest for 3 years. At the end of each year, he paid Rs 500. How much amount should he pay at the end of the 3rd year to clear the debt?

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 9

Amount after 1 yr = 4000[1 + 8/100] = 4320
Paid 500, so P = 4320 – 500 = 3820
Amount after 2nd yr = 3820[1 + 8/100] = 4125.6
So P= 4125.6-500 = 3625.6
Amount after 3rd yr = 3625.6[1 + 8/100] = 3915.6

The average price of 10 books is Rs. 12 while the average price of 8 of these books is Rs. 11.75. Of the remaining two books, if the price of one book is 60% more than the price of the other, what is the price of each of these two books?

Detailed Solution for Cognizant Aptitude Questions and Answers - Question 12

Given that, Total price of the two books = Rs. [(12 x 10) – (11.75 x 8)] = Rs. (120 – 94) = Rs. 26
Let the price of one book be Rs.x
Then, the price of another book = Rs. (x + 60% of x )= x + (3/5)x= (8/5)x
so, x +(8/5)x=26 , x=10
The prices of the two books are Rs. 10 and Rs. 16

The total of 11 results = 11 x 50 = 550
The total of first 6 results = 6 x 49 = 294

The sixth result is common to both:
Sixth result = 294 + 312 – 550 = 56
