Answer :
Valli found out that the town was six miles from her village. The fare was thirty paise
one way. The trip to the town took forty-five minutes. On reaching the town, if she
stayed in her seat and paid another thirty paise, she could return home on the same
bus. She found out these details by listening carefully to the conversations between her
neighbours and the people who regularly used the bus. She also gained information by
asking them a few questions.
