Find the ratio of the following: (a) Speed of a cycle 15 km per hour to the speed of scooter 30 km per hour. (b) 50 m to 10 km (c) 50 paise to ₹ 5

(a) Speed of cycle = 15 km/hr
Speed of scooter = 30 km/hr
Hence ratio of speed of cycle to that of scooter = 15:30 = 1/2 = 1:3

(b) ∵ 1 km = 1000 m
∴ 10 km = 10 x 1000 = 10000 m
∴ Ratio = 5m/10000m = 1/2000 = 1 : 2000

(c) ∵ 1 = 100 paise
∴ ₹ 5 = 5 x 100 = 500 paise
Hence Ratio = 50 paise/500 paise = 1/10 = 1:10
