A1150

B1055

C1120

D1200

Answer:

D. 1200

Read Explanation:

⇒ 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
