Question
Sumita stood on the road for half an hour and counted the number of vehicles passing by. She made a tally mark for each vehicle. This helped her in counting the total number of vehicles in each group.
- Write the number of each vehicle in the table.
- How many vehicles in all did Sumita see on the road in half an hour?
- Auto rickshaws are thrice the number of trucks — true/false?
- Make tally marks for 7 more buses and 2 more trucks.
Solution
- Total number of vehicles seen by Sumita in half an hour
= 28 + 12 + 18 + 15 + 24 + 6
= 103 - Number of trucks = 6
Number of auto rickshaws
= 3 × 6
= 18
So, the number of auto-rickshaws is thrice the number of trucks.
Thus, the given statement is true. - Tally marks for 7 more buses =
Tally marks for 2 more trucks =
