Views:198932
Aptitude test forms a part of the first round of Cognizant recruitment process. It evaluates the candidate's proficiency in mathematical topics, including basic arithmetic, algebra, number system, geometry, probability, permutation & combinations, clocks, calendars, etc. Here, we have provided some practice questions, based on Quant section of Cognizant written test:
###### Cognizant Aptitude Questions
1. Three cubes of edges 6 cms, 8 cms and 10 cms are meted without loss of metal into a single cube. The edge of the new cube will be:
1. 8 cms
2. 12 cms
3. 14 cms
4. 16 cms
Volume of new cube = Volume of cube 1 + cube 2 + cube 3 = 63 + 83 + 103, = 216 + 512 + 1000
a3 = 1728,
a = (1728)1/3 = 12
1. If 378 coins consist of rupee, 50 paise and 25 paise coins, whose values are proportional to 13 :11 : 7, the number of 50 paise coins will be :
1. 128
2. 132
3. 133
4. 136
If values are proportional to 13 : 11 : 7, then the number of coins will be proportional to 13/1 : 11/0.50 : 7/0.25 ⇒ 13 : 22 : 28. Now from this the number of coins of 50 paise will be 378 × 22/63 = 132.
2. A person travels 48 kms at 12 kms/hour and further 48 kms at 16km.s/hour. His average speed for the whole
1. 14 km/hour
2. 13(4/7)km/hour
3. 12(5/7)km/hour
4. 13(5/7)km/hour
Avg. Speed = (Total Distance / Total Time)
TD = 48 + 48= 96,
T1 = 48/12 = 4hrs
T2 = 48/16 = 3hrs
T1 + T2 = 4 + 3 = 7
Avg Speed = 96/7 = 13(5/7) km/hr
1. Simplify (0.001344 / 0.3 x 0.7) = ?
1. 0.0064
2. 0.064
3. 0.64
4. 6.4
(0.001344 / 0.3 x 0.7) = 0.0064
2. The difference of two numbers is 11 and one fifth of their sum is 9. The numbers are :
1. 31, 20
2. 30, 19
3. 29, 18
4. 28, 17
x − y = 11, x + y = 5 × 9 x − y = 11, x + y = 45, y = 17, x = 28
1. How many numbers between 1 and 100 are divisible by 7 ?
1. 9
2. 11
3. 17
4. 14
No. of divisible by 7 7, 14 --------- 98, n = a + (N - 1)d
98 = 7 + (N - 1) 7, 98 = 7 + 7N - 7
98/7= N = 14
2. What is the number which when multiplied by 13 is increased by 180?
1. 13
2. 15
3. 23
4. 35
13 × 15 = 195
3. In 24 minutes, the hour hand of a clock moves through an angle of:
1. 60°
2. 24°
3. 12°
12 hour = 360°, 1 hr. = 360/12 = 30° 60 min = 30°, 1 min 30/60 = .5° 24 min. = 1/2 ×24 = 12°
4. √0.0081 is equal to :
1. 0.09
2. 0.9
3. ±0.08
4. 0.81
