There are 40 passengers in a bus,some with Rs 3 tickets and remaining with Rs 10 tickets.Find how many passengers have tickets worth Rs 3? class 8​

Answer 1

heya buddy!

Answer:

15 passengers

Step-by-step explanation:

Let number of passengers having ticket worth Rs.3 be x

So, total cost of x tickets = 3x

Let number of passengers having ticket worth Rs.10 be y

So, total cost of y tickets = 10y

Since we are given that there are 40 passengers in bus.

So,$x+y-40$ . --1

We are also given that the total collection from these passengers is rs.295.

So,  $3x+2y=295$ --2

Substitute the value of x from 1 in 2

So,  $3(40-y)+10y= 295\\ 120-3y+10y= 295 \\120+7y= 295\\ 7y= 175\\ y= 25$

 

 

 

 

Substitute the value of y in 1

$x+25=40\\x=15$

So, 15 passengers  have tickets worth rs.3
