Question

Out of 15 persons, 14 persons spent Rs. 75 each for their meals. The 15th person spent 70 more than the average expenditure of all the fifteen. The total money spent by all of them was?

• A. 1150
• B. 1055
• C. 1120
• D. 1200

Answer 1

Answer:

D. 1200

⇒ Let the average expenditure be ‘x’, As, 14 people spend Rs. 75 each and 15th person spend Rs. 70 more than the average of all persons ⇒ (14 × 75 + x + 70)/15 = x ⇒ (1050 + x + 70) = 15x ⇒x=80 Total expenditure = 14 × 75 + (80 + 70) = 1200
