Question
Four friends ('W', 'X', 'Y', and 'Z') went to dinner and
received a bill of Rs. 1,800. They agreed that 'W' would pay half of what the other three paid together. 'X' contributed 10% less than what 'W' paid. 'Y' and 'Z' each paid Rs. 50 more than 'W'. Find the amount paid by 'X'.Solution
ATQ,
Let the amount paid by 'W' be Rs. 'y'.
So, the amount paid by 'X', 'Y', and 'Z' together = 2y.
Thus, we have:
y + 2y = 1800
3y = 1800
y = 600
Now, amount paid by 'X' = 600 - (0.10 × 600) = 600 - 60 = Rs. 540.
