Flipkart GRiD Aptitude Quiz-3

Explanation:
Distance = Speed × Time
Upstream distance = (20 - x) km/h × 6 hours = 6(20 - x) km
Downstream distance = (20 + x) km/h × 3 hours = 3(20 + x) km
6(20 - x) = 3(20 + x)
120 - 6x = 60 + 3x
9x = 60
x = 60/9 = 6.67 km/h

Explanation:
Since,
Harry has no brother or sister, so he is his father’s only son.
So, the wife of Harry’s father’s son = is Harry’s wife.
Thus, Harry’s wife is the boy’s mother and the boy is Harry Potter’s son.

Explanation:
Distance covered by 1st Cyclist = 25 km/h × (t + 2) hours
Distance covered by 2nd Cyclist = 30 km/h × t hours
Total Distance =300 km
Solving the above equations
25(t + 2) + 30t = 300
t = 250/55 ≈ 4.55 hours
Since we need to find the total time taken for them to meet, we add the additional 2 hours for the first cyclist:
Total time = t + 2 = 4.55 + 2 ≈ 6.55 hours

Explanation:
Each letter of the word is replaced with the letter tcap comes 4 places after it in the English alphabet.
Applying the same pattern to the word CIRCLE, we get GJOPRN.

Explanation:
Distance = Speed × Time
Distance covered by Atulya= 10 m/s × t seconds
Distance covered by Mayank= 8 m/s × t seconds
10t + 8t = 800
t ≈ 44 seconds

Explanation:
Robert Zane's position is 7th from the top and 28th from the bottom
Total number of students = 6 + Robert Zane [1] + 27 = 34

Explanation:
Time taken by Atulya to complete one lap = 800 meters / 15 m/s = 53.33 seconds
Time taken by Aashay to complete one lap = 800 meters / 12 m/s = 66.67 seconds
They will meet every time it takes for them to cover half the distance of the track, which is 400 meters.
Relative speed = Speed of Alice + Speed of Bob
Relative speed = 15 m/s + 12 m/s
Relative speed = 27 m/s
Time taken to meet = 400 meters / 27 m/s ≈ 14.81 seconds
Number of times they meet = Time taken to complete one lap / Time taken to meet Number of times they meet = 53.33 seconds / 14.81 seconds ≈ 3.6 times

Explanation:
In each pair:
1st letter is a Vowel and 2nd letter is on the place in English Alphabet on Multiple of 5.

Explanation:
LCM = 2 * 2 * 2 * 3 * 3 = 72
Now, we need to find the smallest three-digit number divisible by 72. We start by finding the smallest multiple of 72 greater than or equal to 100: 72 * 2 = 144

Explanation:
This follows the pattern of Sport : Playing Area.
In the first pair, "Football" is played on a "Field."
Applying the same pattern to the second pair,
"Basketball" is played on a "Court."
