Answer 1

Answer:

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.

Hope it helped!

Answer 2

$\huge\bold\red{Hey}$

percentage of friends didn't came in the party =100%-90%=10%

let the total number of friends be x

$10\% \: of \: x = 3$

$\frac{10}{100} \times x = 3$

$\frac{1}{10} \times x = 3$

$x = 3 \times \frac{10}{1}$

$= > x = 30$

therefore the total number of friends Rohan have =30
