Hi,
1 ) Let the number of students in a
group = x
amount each student paid
for boat = Rs 10
Total amount paid by the group to
the boat = Rs10x -----( 1 )
2) If 3 students joins the group then
the total students = ( x + 3 )
Fare of each student = ( 10 - 2 ) = Rs 8
Now total amount paid by the new
group = Rs (x + 3 ) 8
= 8x + 24 ----( 2 )
According to the problem given ,
( 1 ) = ( 2 )
10x = 8x + 24
10x - 8x = 24
2x = 24
x = 24/2
x = 12
Therefore ,
Number of students in the
boat = x = 12
I hope this helps you.
