Mean x = Sum of nos. / Count of numbers = 585/9 = 65 = x
Median y = Middle term when number are arranged in ascending order = 63 = y
Mode z = Number which is present maximum number of times = 81 = z
=> x*y*2*z/5 = 65*63*2*81/5 = 132678
A merchant has 640 kg of sugar, part of which he sells at 2% loss and the rest at 6% profit. He gains 3% on the whole. What is the difference between the quantities of sugar sold at 2% loss and that sold at 6% profit?
(Quantity of Cheaper)/(Quantity of Dearer) = (Price of Dearer - Mean Price)/(Mean Price - Price of Cheaper)
(Quantity of Cheaper)/(Quantity of Dearer) = (106 - 103)/(103-98) = 3/5
Total Quantity = 640 KG
The quantity sold at 2% loss is = (3/8) * 640 = 240 Kgs
The quantity sold at 6% profit is = (5/8) * 640 = 400 Kgs
Difference between Quantity = 400-240 = 160 Kgs
