Explanation

The sequence follows a pattern of dividing by 2:

64 ÷ 2 = 32

32 ÷ 2 = 16

16 ÷ 2 = 8

8 ÷ 2 = 4

This is a geometric sequence with a common ratio of ½.

Explanation

1 million is equal to 10,00,000 (10 Lac)

1 billion = 1,000 million.

1 billion = 100 crores.

1 billion has 9 zeroes

Explanation

To find the amount of milk in the mixture:

300 ml (total mixture) × 0.80 (80% pure) = 240 ml (milk)

Explanation

To solve this problem, calculate the total hours worked by the men:

12 men × 8 hours/day × 10 days = 960 hours

Now, find the number of men needed to complete the work in 5 days, working 12 hours a day:

Let x be the number of men.

x men × 12 hours/day × 5 days = 960 hours

x × 60 = 960

x = 16

Explanation

To determine which number does not possess a square root, examine the options:

525: √525 is not a whole number

900: √900 = 30

81: √81 = 9

9: √9 = 3

Explanation

To simplify the expression:

2√3 + 4√12

First, simplify √12:

√12 = √(4 × 3) = √4 × √3 = 2√3

Now, substitute:

2√3 + 4(2√3) = 2√3 + 8√3 = 10√3
