In a maths class of 30 pupils, 40% are girls. 1 out of 3 pupils also studies physics. Half the boys have a mobile phone, whilst 6 girls have them. Three of the girls have a boyfriend at the moment.
- What percentage of the class are boys?
- How many boys are there in the class?
- What number of pupils also study physics?
