The number of dishes Sandrine washed was 10 more than the number of bananas Charles cooked. Also, the number of bananas Charles cooked was 3 times the number of pears he picked. If Charles picked 50 pears, how many dishes did Sandrine wash?
If the bananas Charles cooked were 3 times the number of pears he picked, then Charles cooked 3*50 = <<3*50=150>>150 bananas.
Since all the dishes that Sandrine washed were 10 more than the number of bananas Charles cooked, Sandrine washed 150+10 = 160 dishes.
#### 160
