The income for 5 days calculated by a man are the following :
₹760, ₹820, ₹745, ₹782 and ₹779.
If the average income is ₹775 for 6 days, then what is the income (in ₹) on the sixth day?
The sum of income of 5 days
= ₹760 + ₹820 + ₹745 + ₹782 + ₹779
= ₹3886
Let the income on the sixth day be ₹x
Average income for six days = ₹775
Total income for six days
= 775 × 6 = ₹4650
As per question,
₹3886 + ₹x = ₹4650
⇒ ₹x
= ₹4650 - ₹3886 = ₹764
