The average cost of 5 items in a shopping list is Rs 650. If one more item whose cost is Rs 1400 is added to the list what will be the new average (in Rs)?
Average cost of 5 items = Rs. 650
=> Total cost of 5 items = $$650\times5=Rs.$$ $$3250$$
New cost when an item with cost Rs. 1400 is added = $$3250+1400=Rs.$$ $$4650$$
$$\therefore$$ New average = $$\frac{4650}{6}=Rs.$$ $$775$$
