Answer 1

Heya friend ! Here is your answer:

As we know 1 percent = 1/100

So, we can write 30percent is 30/100

$30 \: percent \: of 400 is \frac{30}{100}×400$

1. ans - 120

2. 250

3. 20

As you said 1 minute So, I can't write in detail.

In all question use the formula( 30 percent of 400 I have shown in this process you can do all)

Hope it helps friend :-)
