Find the ratio of the following: - Speed of a cycle \(15\) km per hour to the speed of scooter \(30\) km per hour.
- \(5\) m to \(10\) km
- \(50\) paise to Rs \(5\)
- Speed of a cycle \(15\) km per hour to the speed of scooter \(30\) km per hour.
- \(5\) m to \(10\) km
- \(50\) paise to Rs \(5\)
Solution and Explanation
(a) Ratio of the speed of cycle to the speed of scooter = \(\frac{15}{30}\)
= \(1:2\)
(b) Since \(1\) km = \(1000\) \(m\),
Required ratio = \(\frac{5\; km}{10\;km}\)
= \(\frac{5\;m}{10}× 1000\; m\)
= \(1:2000\)
(c) Since Rs \(1 = 100\) \(\text{paise}\),
Required ratio = \(\frac{50 \;paise}{Rs \;5}\)
= \(\frac{50 \;paise}{500 \;paise}\)
= \(1:10\)
Top Questions on Recalling Ratios and Percentages
- There are 938 players played cricket in the world and some of them are played different-different leagues APL, BPL, and CPL in the world. There are 56 \(\frac{8}{7}\) % of players who do not play in any league.BPL has 4 more players as compare to CPL and APL have 22 players less than the CPL. The ratio between the players who play in only APL & CPL together to the players who play only BPL & CPL together is 3 : 2. The total number of players who play only in APL and BPL is equal to the sum of the players who play in only APL & CPL together and BPL & CPL together. The total number of players who play in all three leagues is 99 less than to the players who play in BPL. 40% of the players who play in all three leagues are playing in APL and CPL together.
