Explanation

Let the length and the breadth of the floor be l m and b m respectively.

l = b + 200% of b = l + 2b = 3b

Area of the floor = 324/3 = 108 sq m

l b = 108 i.e., l * l/3 = 108

l2 = 324 => l = 18.

Explanation

Square of a proper fraction is always smaller than itself.

Means the square of the improper fraction is greater than the given fraction.

Explanation

Let numbers are x and y

⇒x−y=5

xy=336

Now using identity

(x+y)

2

 =(x−y)

2

 +4xy

=25+4(336)

=25+1344

=1369

⇒x+y=37

Explanation

Let's check each option directly for being a sum of two primes:

7 = 2 + 5 (both prime)

19 = 2 + 17 (both prime)

31 = 2 + 29 (both prime)

For 23:

2 + 21 = 23 (21 is not prime)

Explanation

Given:

√(2.3 × 10⁹)

Break it down:

= √(2.3) × √(10⁹)

≈ 1.52 × 10⁴ × √10³ (since 10⁹ = 10⁶ × 10³ and √(10⁶) = 10³)

≈ 1.52 × 10⁴ × 31.62

≈ 48000

Among the given options:

≈ 50000

Explanation

To find the closest value, let's calculate 29.8 × 9.8:

29.8 × 9.8 = 292.04

Comparing this to the given options:

• 3000 is too large
• 2800 is close but slightly less
• 100 is too small
• 300 is the closest

The answer is 300.

Explanation

Terminating and recurring decimals both represent rational numbers.

Terminating decimals have a finite number of digits after the decimal point,

Recurring decimals have an infinite number of digits that repeat in a pattern.

Explanation

1200 ÷ 4 = 300
