Answers
Answer:
Friday : Rs 580
Saturday : Rs 150
Step-by-step explanation:
When a person calculated his expenses from Sunday to
Thursday, he found the average expenditure to be 400 rupees
per day. Including Friday, the average increased to 430 rupees
per day How much did he spent on Friday? Including Saturday
the average decreased to 390 rupees per day. How much did
he spend on Saturday?
Sunday to Thursday = 5 Days
average expenditure = Rs 400
Total Expense Sunday to Thursday = 400 * 5 = Rs 2000
Sunday to Friday = 6 Days
average expenditure = Rs 430
Total Expense Sunday to Friday = 430 * 6 = Rs 2580
Friday expense = 2580 - 2000 = Rs 580
Sunday to Saturday = 7 Days
average expenditure = Rs 390
Total Expense Sunday to Saturday = 390 * 7 = Rs 2730
Saturday Expense = 2730 - 2580 = Rs 150
