In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for the both quantities and choose the correct option.

Quantity A: A positive number is such that adding its square root to itself gives another number equal to twice the first number. Find number?

Quantity B: A number which is greater than 2 is such that adding square of that number to itself gives another number equal to 3 less than 5 times of the given number. Find number?


1). Quantity A > Quantity B
2). Quantity A < Quantity B
3). Quantity A ≥ Quantity B
4). Quantity A ≤ Quantity B

Let the number is ‘x’,

So x + √x = 2x

⇒ √x = 1

⇒ x = 1

Solving for Quantity B:

Let the number is ‘x’

So, x2 + x = 5x – 3

⇒ x2 – 4x + 3 = 0

⇒ (x – 3)(x – 1) = 0

According to question x is greater than 2 so x = 3

Thus, Quantity A < Quantity B
