If the selling price of 16 cows is equal to the cost price of 20 cows, then find the gain or loss percentage. This question is asked in mock test of SSC CGL, CHSL competition exam.

Another method of asking this question in everywhere is

**If the selling price of 16 items is the same as the cost price of 20 items, then there is a loss or gain.**Solution :-

Lets Suppose the Selling price of 1 cow or item is Rs. 1

Then the Selling price of 16 Cows or items = Rs. 16.

Hence, as given in the question that,

The cost price of 20 cows or items is equal to the selling price of 20 cows or items.

that means,

CP of 20 cows = Rs. 16

CP of 1 cow = 16 / 20 = 4 / 5

= Rs. 4/5 = Rs. 0.8

Now, profit percent on each cow = profit / CP x 100

profit % = SP of each cow - CP of each cow / CP x 100

Profit % = (1 - 4/5 = 1 / 5 = Rs. 0.2) 0.8 / x 100

= 0.2 / 0.8 x 100

= 2/8 x 100

= 25%

One More Example to illustrate the answer.

**Q. The Cost price of 25 toys is equal to the selling price of 20 toys. find gain or loss percent.**

Lets Suppose the cost price of 1 toy or item is Rs. 1

Then the cost price of 25 toy = Rs. 25.

Hence, as given in the question that,

The cost price of 25 toys is equal to the selling price of 20 toys.

that means,

SP of 20 toys = Rs. 25

SP of 1 toy = 25/20 = 5/4 = 1.25

gain = SP - CP = 1.25 - 1.00 = .25

Gain % = .25 / 1 x 100 = 25 %
