A group of 5 friends went to a restaurant. If 4 of them paid Rs. 200 each and the fifth paid Rs. x, the average bill per person came out to be Rs. 210. What is the value of x?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ₹250
Average = Total / Number
210 = (200 × 4 + x) / 5
210 × 5 = 800 + x
1050 = 800 + x
x = 1050 − 800
x = 250
