Question

John invited 50 people to his birthday party. Every 5 boys ate 3 bowls of wanton mee. Every 3 girls ate 2 bowls of wanton mee. In total, 32 bowls of wanton mee were eaten. How many girls were there in the birthday party?

Answer

If there were 5u boys, there were ( 50 – 5u ) girls in the party. So

5u*3/5 + 2( 50 -5u ) /3 = 32          

3u +  ( 100 – 10u )/3 = 32                   multiply both sides by 3

9u + 100 – 10u = 96

u = 4

50 – 5u = 50 – 20 = 30

30 girls were in the party.

Check: 30* 2/3 + 20 * 3/5 = 20 + 12 = 32 Checked
