Question 1092474: in a picnic, a total bus fare of rs 360 is to be equally paid by a number of passengers. if there were 3 passengers more, each would have paid rs 6 less. find the number of passengers. Answer by ikleyn(52803) (Show Source):
Let x be the number of passengers under the question.
Then each pays rs for a ticket.
Had be the 3 more passengers, each would pay rs .
The condition says that the difference of ticket price would be rs 6.
It gives you an equation
- = 6. (1)
Cancel the factor 6 in both sides. You will get
- = 1. (2)
Solve this equation to get the answer x = 12.
I solved it mentally.
Actually, the regular procedure of solution starts with multiplying both sides of the equation (2) by x*(x+3).
The rest is just technique and arithmetic.
