A grocer has a sale of Rs. 5400, Rs. 9000, Rs. 6300, Rs. 7200 and Rs.4500 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs. 5600?  Choose the correct choice:  A) s. 1200  B) s. 5400  C) s. 5400  D) s. 4999  E) s. 5000
Total sale for 5 months = Rs. (5400 + 9000 + 6300+ 7200 + 4500) = Rs. 32400.   Required sale = Rs. [ (5600 x 6) - 32400 ]   = Rs. (33600 - 32400)   = Rs.1200.   Option s. 1200
