Tina had to sew 258 jumpsuits. She sewed 8 jumpsuits 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 Tina finish sewing all the jumpsuits? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Tina sewed on the first week = 5

Number of jumpsuits that Tina completed for from Monday to Sunday on the first week
= 5 x 8 + 2 x 11 
= 40 + 22
= 62

Number of jumpsuits left to sew
= 258 - 62
= 196

Number of jumpsuits that Tina could sew per week from second week onwards
= 5 x 8 + 2 x 11
= 40 + 22
= 62

Number of weeks that Tina needed to sew 196 jumpsuits
= 196 ÷ 62
= 3 r 10

Number of days that Tina needed to sew 10 jumpsuits
= 10 ÷ 8
= 1 r 2

Tina needed 1 more day to finish sewing the remaining 2 jumpsuits.

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