Answer:
i) 1.25m
ii) 32 books
Step-by-step explanation:
60 identical books occupies = length of 1.5m
(i) the length occupied by 50 such books on
a shelf,
If:
60 books = 1.5m
50 books = y m
60 × ym = 1.5 × 50
ym = 1.5 × 50/60
= 1.25 m
Therefore, 50 of such books occupies a length of 1.25m
(ii) the number of such books needed to completely
occupy a shelf that is 80 cm long.
100 cm = 1m
80 cm = x m
Cross Multiply
xm = 80/100
= 0.8 m
If : 1.5 m = 60 books
0.8 m = y books
Cross Multiply
= 1.5m × y books = 60 books × 0.8m
y books = 60 books × 0.8m/1.5m
y books = 32 books
Therefore, 32 books occupies a shelf that is 80 cm or 0.8 m long
Number of students N, y years
N = 700 + 50y
N = 700 + 50 x 10 = 1200 (C)
Left not painted percentage = 100 - 60 = 40 %
Left = 40/100 x 45 = 18 (H)
