Answer: a) There are 10 × 10 = 100 boxes in all.
b) Since there are 100 equal boxes, each box is 1/100 of the sheet.
There are 10 blue boxes. So, the blue portion is 10/100 of the sheet.
10/ 100 = 1/10 = 0.10 = 0.1
c) There are 100 paise in one rupee. Therefore,
10 paise = 10/100 rupee = 1/10 rupee = 0.10 rupee = 0.1 rupee
d) There are 15 red boxes. Since the sheet is divided into 100 equal boxes, the red colour is 15/100 of the sheet.
15/100 = 0.15
So, the red colour is 0.15 of the sheet.
e) 3/100 of the sheet is black.
3/100 = 0.30
Therefore, 0.30 of the sheet is black.
f) There are 22 white boxes on the sheet. 22/100 part of the second sheet is white.

Arun’s father’s salary = 2000 Sri Lankan Rupees
