on school picnic,a group of students agree to pay equally for the use of a full boat and pay Rs.10 each.if there had been 3 more students in each group, each would have paid Rs.2 less.how many students were there in the group?
Something does not make sense. If the boat is full while paying 10, wouldn't adding 3 students overload the boat? Also some data is missing. What is the total charge for the boat?
On a school picnic , a group of boys agree to pay equally for the use of a boat and each pays Rs 40. If there had been 5 more boys in the group, each would have to pay Rs 10 less. How many boys were in the group?
To find the number of students in the group, let's assume that there are 'x' students in the group initially.
According to the given information, if there had been 3 more students in each group, each student would have paid Rs.2 less.
So, when there are 'x' students, each student pays Rs.10, and when there are 'x+3' students, each student pays Rs.8 (Rs.10 - Rs.2).
We can set up the following equation based on the given information:
x * 10 = (x + 3) * 8
Now, let's solve this equation to find the value of 'x'.
10x = 8(x + 3)
10x = 8x + 24
10x - 8x = 24
2x = 24
Dividing both sides by 2:
x = 12
Therefore, there are 12 students in the group.
