Question

A man sold 250 chairs and had a gain equal to SP of 50 chairs. what is his profit percent ?​

Answer 1

Answer:

a man sold = 250 chairs

Gain = SP of 50 chairs

A/q

we know that profit percent =

profit * 100/Cp

so, we suppose sp be X

cp= 250-50x

gain%=50x*100/250-50x

so,gain%=5000/200

answer is =25%

Answer 2

Answer:

let SP be x

Now,

total SP = 250x

gain = 50x

CP = 250x - 50x = 200x

$profit \: \% \: = profit \times 100 \div cp \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 50x \times \frac{100}{200x} = 25$

Hence, profit will be 25%
