10 person went to a hotel for taking their meal. 9 of them spent ₹20 each on their meals and the 10th person spent ₹27 more then the average expenditure of all of them. What was the total money spent by all of them?
Answer & explanation
Correct answer: option 1
Let the average expenditure = A
Total expenditure of 9 person = 20 × 9 = 180
Expenditure of 6th person = A + 27
Total expenditure of all person = 10 × A = 10A
ATQ,
180 + (A + 27) = 10A
A + 207= 10A
9A = 207
A = 23
Total expenditure = 10 × 23 = Rs. 230
