Question 954404: on a school picnic, a group of students agree to pay equally for the use of full boat and pay RS 10 each. if there had been 3 more students in a group, each would have paid RS 2 less. how many students were there in a group?' Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! n=number of students
n(RS 10)=(n+3)(RS 8)
RS 10n=(RS 8)(n)+RS 24 Subtract RS 8(n) from each side.
RS 2(n)=RS 24 Divide each side by RS 2
n=12 ANSWER There were 12 students in the group.
CHECK:
n(RS 10)=(n+3)(RS 8)
12(RS 10)=(12+3)(RS 8)
RS 120=15(RS 8)
RS 120=RS 120
