Question

by selling 120 mangoes a person gain a profit equal to the cp of 20 mangoes find the profit percent​

Answer 1

Answer:this is all a matter of carefully writing up the problem.

let’s say that :

P is the sales price per orange

C is the cost per orange

M is the margin per orange

And we define profit percentage as M/P

.

So :

P = C + M

for 120 oranges,

120P = 120C + 120M

.

we are told that the profit for 120 oranges is 20 oranges,

therefore :

120M = 20P

now we can calculate M/P, by first dividing the above equation by 120, then by P:

M = (20/120)P

M/P = 20/120

so M/P = 1/6

and

M/P = 16.67%
