Answer 1

Since 90% of his friends came, 10% of his friends didn't come.
So, let the total no of friends be 'x'.

A/Q,
$\frac{10}{100}*x=3$
x= 30.

Therefore, total no of friends is 30.

Answer 2

30 is the number of total friends Rohan has.

Step-by-step explanation:

Given that,

The percent of friends who attended the party = 90%

The number of friends who didn't come = 3

Now, we can let the number of total friends be x

Friends who didn't come = (100% - 90%)

= 10%

As we know,

10% of x = 3

10/100 * x = 3

10x/100 = 3

x = 300/10

x = 30

∵ The total number of friends is 30.
