Total bill = y

Number of friend will pay the bill = x - z

y/ x - z.

A is the correct answer.

Solution


Given:
    • Total number of friends = x
    • Total cost of meal = y dollars
    • z number of friends decide not to pay

To find:
    • Amount paid by each of the remaining friends

Approach and Working:
    • Number of friends, who pay = x – z
    • Thus, amount paid by each of them = \(\frac{y}{(x – z)}\)

Hence, the correct answer is Option A

Answer: A

E \(\frac{y – x}{z}\)


actual division y/x
since z friends backed out
so
left with x-z
y/x-z
IMO A
