Lemons were bought at Rs 60 a dozen and sold at the rate of Rs 40 per 10. Find the gain or loss percent

Solution:

Lemons were bought at Rs. 60 a dozen which implies Rs. 60 for 12 lemons.

The Cost price (C.P.) can be expressed per lemon as shown below:

C.P. = 60/12 = Rs. 5 per lemon

The selling price is calculated as :

Selling price(S.P.) = 40/10 = Rs. 4 per lemon

The gain or loss percent is calculated as:

S.P. of One lemon - C.P. of one lemon

= Rs 4 - Rs. 5

= Loss of Rs 1 per lemon

The loss percent per lemon is therefore equal to:

Loss % = (Loss/C.P.) × 100

= (1/5) × 100

= 20%

✦ Try this: Lemons were bought at Rs 72 a dozen and sold at the rate of Rs 30 per 6. Find the gain or loss percent.

Lemons were bought at Rs. 72 a dozen which implies Rs. 60 for 12 lemons.

The Cost price (C.P.) can be expressed per lemon as shown below:

C.P. = 72/12 = Rs.6 per lemon

The selling price is calculated as :

Selling price(S.P.) = 30/6 = Rs. 5 per lemon

The gain or loss percent is calculated as:

S.P. of One lemon - C.P. of one lemon

= Rs 5 - Rs. 6

= Loss of Rs 1 per lemon

The loss percent per lemon is therefore equal to:

Loss % = (Loss/C.P.) × 100

= (1/6) × 100

= 16 ⅔ %
