There are 40 passengers in a bus. Some have tickets worth ₹ 3 and remaining have tickets worth ₹10. The total collection from these passengers is ₹ 295. How many passengers have tickets worth ₹ 3?
15
Let the number of passengers having ticket worth ₹ 3, is x
Then the passengers having ticket worth ₹10, is (40−x).
Then,
3x+10×(40–x)=295 3x+400–10x=295 −7x=295–400 −7x=−105 x=−105−7 x=15.
∴ Number of passengers with tickets worth ₹ 3 = 15.
