Question

in Rohan birthday party 90% of his friend came and three friend did not come find the total number of friend Rohan has

Answer 1

Ans = 30 friends

no of friend did not came = 3 = 10%

10% = 3
1% = 3/10
100% =(3/10)*100 =30
total friends =30

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
