(a) The maximum number of children visited the museum on Sunday. Their
number was 3,200.

(b) Number of children who visited the museum on Sunday = 3,200

Number of children who visited the museum on Monday = 1,200
 Diff erence in the number of children = (3,200 – 1,200) children

= 2,000 children

(c) The least number of children visited the museum on Monday, i.e., 1,200.

Number of children who visited the museum on Tuesday = 1,400

 Increase in number of children on Tuesday = (1,400 – 1,200) children

= 200 children

(d) Total number of children who visited the museum in the week
= (1,200 + 1,400 + 1,800 + 2,100 + 2,500 + 2,900 + 3,200) children

= 15,100 children
