Maths 1

2. Herman gave 2/5 of his picture cards to his sister. 2/7 of the remaining cards were given to his brother and he kept the rest. If his brother had 24 cards less than his sister, how many cards had he at first?

3. At a funfair, ¼ of the people were men. 2/11 of the remaining people were women. The rest were children. If there were 320 more children than men, how many people were at the fair?
