Explanation

The series consists of square numbers:

4 = 2^2

9 = 3^2

16 = 4^2

25 = 5^2

36 = 6^2

Explanation

To find the value of x^2, we need to square the value of x:

x^2 = (2)^2

= 2 × 2

= 4

So, the correct answer is: 4

Explanation

The pattern of the series appears to be square numbers:

• 1 = 1^2
• 9 = 3^2
• 25 = 5^2
• 49 = 7^2
• 81 = 9^2
• 121 = 11^2

So, the correct completion of the series would be:

1, 9, 25, 49, 81, 121

Explanation

B covers 28 meters in 7sec. So, B’s time over the course = (7/28)*1000 =250 sec.

Whereas A’s time over the course = 250 -7 = 243 sec.

i.e A’s time over the course is 4min, 3 sec

Explanation

Given:

Zˣ = 32

Since 32 is a power of 2:

32 = 2⁵

So, Zˣ = 2⁵

Now, equate the exponents:

X = 5

Now, find X²:

X² = 5² = 25

Explanation

888/0.8=1110

1110×8=8880

Explanation

The hands of a clock coincide 22 times in a 24-hour day.

• The hour and minute hands coincide once every 65 minutes (60 minutes + 5 minutes).
• Since there are 24 hours in a day, the hands coincide 24 x (24/65) = 22 times in a 24-hour day.
