Answer 1

The correct option is B $Rs60,33\frac{1}{3}\%$

A milkman who wants to make a fast buck using false measure

only 900 ml instead of a liter. Milkman's cost price and

selling price per liter of milk are Rs. 10 and Rs. 12 respectively

what is his profit and profit percentage if he buys 18 liters and sells it .

Ans: cost price per liter = Rs. 10

selling price per liter =Rs. 12

$\therefore$ For purchasing 18 liters of milk , milkman has

to pay, Total cost price $=10\times 18$

T.C.P = Rs. 180

Now since, he sells 900 ml and proclaims

it to be 1 liter , so effectively

for him,

1 liter = 0.9 liter ,

So when he sells 18 liter, he actually

sells,$\frac{18}{0.9}=20$ liter of milk

$\therefore$ Total selling price $T.S.P=20\times 12$

T.S.P = 240 Rs.

$\therefore$ Profit = T.S.P - T.C.P

= 240 - 180

= Rs. 60

Profit percentage = $\frac{profit}{T.C.P}\times 100$

$\frac{60}{180}\times 100$

= 33.33%
