Question

A local bus is carrying 40 passengers ,some with 50 Paise tickets and the remaining with rupee1.50 tickets . if the total receipts from these passengers us rupee 32. find the number of passengers with 50 Paise tickets.

Answer 1

Let the number of passengers with 50 Paise (0.5 Rupee) tickets be x.
Then, number of passengers with 1.50 Rupee tickets would be (40 - x) 
According to question,
0.5x + 1.5(40 - x) = 32
⇒ 0.5x + 60 - 1.5x = 32
⇒ -x + 60 = 32
⇒ x = 28
∴ Number of passengers with 50 Paise tickets is 28.

Answer 2

Answer:

Total amount =32

let the number of passengers with 50paise (0.5rupee)ticket be x

then, number of passengers with 1.50rupee ticket would be (40-x)

A. T. Q

total number of passengers =

rupee 0.50*4+1.50(40-x)=rupee 32

=0.50+60-1.50x=32

x=32-60

-x=-28

x=28

hence, number of passengers with 50paise tickets =28
