Verbal Reasoning - Arithmetic Reasoning - Discussion

Please explain each step clearly. I cannot understand any step.

4 that did not turn up x(x). Total of students == total money used, hence.

4x = 96 = 24.

But since each added 4rs to cover up = 4rsx4 (not turned up) = 16.

Subtract. 24 total of students - 16 = 8.

Quick solution:

96 = total budget.
4 = contribution per person.

Therefore, total number of person attended the picnic equals to
x-4x = 96/4 = x-4x = 24 and then subtract 4x from x which gives you 3x and therefore, 3x = 24 and x = 24/3 = 8.

8 is the total number of persons that attended. Thank you.

4(x-4x) = 96.
4x-16x = 96.
-12x = 96.
x = 8.

Will you please explain, how it comes x square-4x-96?

An unconventional way of solving it, but it's only good if you have multiple choice answers in front of you:

Step 1: 96 (total amount)/8 (Answer A) = $12 (individual contribution).

Step 2: 8 (the # of people attending the picnic) + 4 (who have left) = 12.

Step 3: 96 (total amount)/12 (initial group) = $8.

Step 4: $8 (individual contribution for the group of 12)-$12 (individual contribution for the group of 8) = -4.

Step 5: 12*8 = 96 and 8*12 = 96.

I want simple to solve this question.

What kind of formula do you get? Please answer.

For this type of questions it is easy to verify the options.

1st option: The no. of students attended the picnic is = 8 i.e. after deducting 4 members. If the left 4 members participated then total no. of students will be 12 members and each contribution gets Rs. 8 i.e.12*8=96.

With deducting 4 members increases the contribution of Rs. 4 i.e It gets Rs. 12 as contribution to remaining 8 members i.e 8*12=96.

Therefore the option "A" is the correct answer and we may leave with this answer.

If we not get the correct answer we may check further options also.

I need clarity explanation, anybody can?
