Mrs Tan ordered 82 ice creams to be shared equally by 41 students in her class. All the boys were present but some girls were absent. After giving each student who was in class one extra ice cream each, Mrs Tan still had 1 ice cream left.
a) how many girls were absent?
b) There were twice as many boys as girls who were in her class.
what was the total number of girls in Mrs Tan’s class?
Would need some guide as teacher never marked the question
