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 quickly 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.

• Total number of vehicles seen by Sumita in half an hour = 28 + 12 + 18 + 15 + 24 + 6

= 3 × 6
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 =
