Question

in Rohan's birthday party 90% of his friends came and three friends did not came find the total number of friends Rohan has

Answer 1

% of friends not attended the party = 10%

No.of friends not attended the party = 3

So, 10%. = 3 members

90%. = ?? Members

Cross multiplying,

( 90 ×3) / 10 = 30

90% = 27 members.

Therefore, total no.of members = 27 +3 = 30 members.
