उत्तर
Given, total number of passengers = 40
Let the number of passengers having tickets worth ₹ 3 be x.
Then, the number of passengers having tickets worth ₹ 10 = (40 – x)
Total collection from passengers = ₹ 295 ...[Given]
According to the question,
3x + 10(40 – x) = 295
⇒ 3x + 400 – 10x = 295
⇒ – 7x = 295 – 400
⇒ – 7x = – 105
⇒ x = `-105 xx ((-1)/7)`
∴ x = 15
Hence, the number of passengers having tickets worth ₹ 3 is 15.
