Question

in rohan's birthday party ,90%of his friends came and 3 friends did not come. find the total number of friend rohan has.

Answer 1

If 90% come and 3 not come it means
100% -90% = 10%
10% =3 friends
So 100% is 30 friends

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
