On a school picnic group of students agree to pay equally for the use of a full bought and paid rupees 10 each if there had been three more students in the group which would have paid to rupees less how many students with their in the group ​

Answer 1

Step-by-step explanation:

Hi,

1 ) Let the number of students in a

group = x

amount each student paid

= Rs 10

Total amount paid by the group = 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 = x = 12
