Answer 2

Answer:

20 times of 20% of the number is 80000.

Step-by-step explanation:

Given : If 30 is subtracted from 30% of a number gives 30.

To find : 20 times of 20% of the number ?

Solution :

Let the number be 'x'.

30 is subtracted from 30% of a number gives 30.

i.e. $30\%\text{ of } x-30=30$

$\frac{30}{100}\times x=30+30$

$0.3x=60$

$x=\frac{60}{0.3}$

$x=200$

The number is 200.

Now, 20 times of 20% of the number is given by,

$r=20\times 20\%\text{ of } 200$

$r=20\times 20\times 200$

$r=80000$

Therefore, 20 times of 20% of the number is 80000.
