Question 72

A man sold 18 cots for Rs.16800, gaining there by the cost price of 3 cots. Find the cost price of a cot.

Solution

No of cots = 18

Gain = 3 cots.

% percentage gain = (3 *100)/18 = 16.66%.

Let X would be the CP of 18 cots.

So,

SP = X + 16.66% of X

1.166X = 16800

X = 14400. (Approx.)

CP per cot = 144000/18 = Rs. 800.

D is correct choice.
