Question

Ani, Amit and sunil went out for dinner in a restaurant. Anil paid 1 /3 of the amount of the bill and sunil had enough money to pay 1 /4 of the bill. Amit paid the remaining part. What part of the bill was paid by Amit

Answer 1

Let the bill-amount is x and Amit pay the y part of bill-amount.
A/Q,
amount paid by Anil = x/3amount paid by Sunil = x/4  x/3 + x/4 + y = x⇒ y = x - x/3 - x/4⇒ y = (12x - 4x - 3x)/12⇒y = 5x/12So the part of bill-amount paid by Amit is 5/12.
