Question 103
Solve the following:
There are 40 passengers in a bus, some with Rs. 3 tickets and remaining with Rs. 10 tickets. The total collection from these passengers is Rs. 295. Find how many passengers have tickets worth Rs. 3?
Given, total number of passengers =40
Let the number of passengers having worth Rs. 3 be x.
Then, the number of passengers having tickets worth Rs.10=(40-x)
Total collection from passengers =Rs. 295
According to the question,
3x+10(40-x)=295
⇒3x+400−10x=295⇒−7x=295−400⇒−7x=−105⇒x=−105×(−17)∴x=15
Hence, the number of passengers having tickets worth Rs. 3 is 15.
