300 people attended a party. After one hour, 1/3 of the number of people left the party. after another hour, 3/10 of th remaining people left the party. How many people were left at the party in the end?

Sagot :

1/3 of 300 is 100
So the remaining is 200
3/10 of 200 is 60
So 200-60 is 140
Then 140 people were left at the party in the end
