Question :28

If $(22)^3$ is subtracted from the square of a number, the answer so obtained is 9516. What is the number?

Answer: (a)

Let the number be x.

Now, according to the question,

$x^2 – (22)^3$ = 9516

or, $x^2$ = 9516 + $(22)^3$ = 9516 + 10648 = 20164

⇒$x = √{20164}$ = 142

Question :29

$(41)^2 + (38)^2 × (0.15)^2$ = ?

Answer: (a)

? = $(41)^2 + (38)^2 × (0.15)^2$
