Gem had to sew 118 blouses. She sewed 6 blouses each day from Monday to Friday and 11 each day on Saturday and Sunday. Starting on a Monday, on which day of the week did Gem finish sewing all the blouses? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Gem sewed on the first week = 5

Number of blouses that Gem completed for from Monday to Sunday on the first week
= 5 x 6 + 2 x 11 
= 30 + 22
= 52

Number of blouses left to sew
= 118 - 52
= 66

Number of blouses that Gem could sew per week from second week onwards
= 5 x 6 + 2 x 11
= 30 + 22
= 52

Number of weeks that Gem needed to sew 66 blouses
= 66 ÷ 52
= 1 r 14

Number of days that Gem needed to sew 14 blouses
= 14 ÷ 6
= 2 r 2

Gem needed 1 more day to finish sewing the remaining 2 blouses.

Day of the week that Gem completed her sewing
= 2 + 1
= 3 (Wed)

Answer(s): 3
