In a group of 5 persons, 4 person spent Rs 500 each for their shopping and remaining one spent Rs 100 more than the average expenditure of all the 5 persons. Find total expenditure for their shopping.
1). Rs. 2700
2). Rs. 2625
3). Rs. 2725
4). Rs. 2525
Let the fifth person expenditure be Rs x
According to the question
⇒ {(500 × 4) + x}/5 + 100 = x
⇒ x = 625
∴ Total expenditure of all five persons = 500 × 4 + 625 = Rs. 2625
