Question

If 120 is 20% of a number, then 120% of
that number will be
(1) 20
(2) 120
3) 480
(4) 720​

Answer 1

Answer:

(4) 720

Step-by-step explanation:

Let the required number be x.

Given that,

20% of that number is 120

Therefore, forming an eqn based on given condition, we will get,

=> 20% of x = 120

Therefore, we will get,

$= > \frac{20}{100} \times x = 120 \\ \\ = > x = \frac{120 \times 100}{ 20} \\ \\ = > x = 6 \times 100 \\ \\ = > x = 600$

Therefore, the required number is 600.

Now, to find the 120% of that number,

= 120 /100 × 600

= 120 × 6

= 720

Hence, the required answer is (4) 720
