Question from rm, a student:
a woman washing a large number of dishes after a meal was asked how many people attended the meal. she did not know but 'every two used a dish of rice between them, every three a dish for soup and every four a dish for meat, and there were 65 dishes in all.' how many people were there?

Rephrase that: every person used half a dish of rice....
How many dishes (as a fraction) did each person use in total?
And how many times does this go into 65?

Good Hunting!
