Fanny had to sew 212 coats. She sewed 8 coats each day from Monday to Friday and 13 each day on Saturday and Sunday. Starting on a Monday, on which day of the week did Fanny finish sewing all the coats? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Fanny sewed on the first week = 5

Number of coats that Fanny completed for from Monday to Sunday on the first week
= 5 x 8 + 2 x 13 
= 40 + 26
= 66

Number of coats left to sew
= 212 - 66
= 146

Number of coats that Fanny could sew per week from second week onwards
= 5 x 8 + 2 x 13
= 40 + 26
= 66

Number of weeks that Fanny needed to sew 146 coats
= 146 ÷ 66
= 2 r 14

Number of days that Fanny needed to sew 14 coats
= 14 ÷ 8
= 1 r 6

Fanny needed 1 more day to finish sewing the remaining 6 coats.

Day of the week that Fanny completed her sewing
= 1 + 1
= 2 (Tue)

Answer(s): 2
