The correct answer is Rs 6300.
Given: Number of people = 45.
Average expense of one person per day = Rs 20.
To Find: Total expenses for all the persons for a week.
Solution:
Average expense of one person per day = Rs 20.
Expense of 45 people in one day = 20*45 = Rs 900
1 Week = 7 days.
Expense of 45 people in 1 week = expense of one day * 7
Expense of 45 people in 1 week = 900 * 7
Expense of 45 people in 1 week = 6300
Hence, the total expense all persons for a week is Rs 6300.
