Question

: In Rohan's birthday party, 90% of his friends came and three friends did not come. Find
the total number of friends Rohan has ​

Answer 1

270

90÷100×30

=270-3

267

Answer 2

Answer:

Let total number of friends = x

And As given 90% of his friends came and 3 didn't't came , So we get

x - 90% of x = 3

x - 90x100 = 3

Taking LCM we get

100 x − 90 x100 = 3

100 x - 90 x = 300

10 x = 300

x = 30

So,

Rohan have total number of friends = 30 ( Ans )
