(a)
(i) y+5
(ii) y–3
(iii) 6y
(iv) 6y–2
(v) 3y+5
(b) Length = 3b and Breadth = (3b–4) meters
(c) Height of the box = h cm
Length of the box = 5 times the height = 5h cm
Breadth of the box = 10 cm less than length = (5h–10) cm
(d) Meena’s position = s
Beena’s position = 8 steps ahead = s+8
Leena’s position = 7 steps behind = s–7
Total number of steps = 4s–10
(e) Speed of the bus = v km/h
Distance travelled in 5 hours = 5v km
Remaining distance = 20 km
Therefore, total distance = (5v+20) km
