Flipkart GRiD Aptitude Quiz-1

Explanation:
The prime factorization of each number is as follows: 18 = 2 * 3 * 3 25 = 5 * 5
To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: LCM = 2 * 3 * 3 * 5 * 5 = 450
Now, we need to find the smallest six-digit number divisible by 450. We start by finding the smallest multiple of 450 greater than or equal to 100,000: 450 * 223 = 100,350
Therefore, the smallest six-digit positive integer that is divisible by both 18 and 25 is 100,350.

Explanation:
67 is a prime number.
27, 45, and 56 are Composite numbers.

Explanation:
The prime factorization of 9 is 3^2. The prime factorization of 16 is 2^4.
To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: LCM = 2^4 * 3^2 = 144.
Now, we need to find the smallest multiple of 144 which is a six-digit positive integer. We start by finding the smallest multiple of 144 greater than or equal to 100,000
144 * 695 = 100080.

Is the correct sequence of telling the process of Extraction of Gold through the Mining Process.

Explanation:
Probability of drawing two non-red balls: The first ball drawn has a probability of 7/12 of being non-red. The second ball drawn, without replacement, has a probability of 6/11 of being non-red.
The complementary event of drawing two non-red balls is drawing at least one red ball. So, the probability of drawing at least one red ball is 1 - 7/22 = 15/22.
Hence, the probability that at least one of the balls drawn is red is 15/22=>45/66.

Explanation:
In this case, the statement clearly states tcap “Smoking is harmful to health.” Argument 1 supports the statement by proposing a ban on smoking to protect people's health.
Where as, Argument 2 is simply promoting an Unhealthy lifestyle.

Explanation:
Probability of selecting the first green ball = 5/12 Probability of selecting the second green ball (after drawing one green ball) = 4/11 Probability of selecting a non-green ball (after drawing two green balls) = 7/10
Probability of exactly two green balls = (5/12) × (4/11) × (7/10)
=>140/(12 × 11 × 10)
=>140/132 => 5/66
Probability of exactly two green balls (considering all possible arrangements) = 3 × (5/66)
=>15/66
