Question

a man sold two painting at rupees 924 one he gains 20% and another he losses 20% how much does a gains or loss in whole transaction ​

Answer 1

Step-by-step explanation:

Cost price (in the case of gain)=

$\frac{100}{100 + p\%} \times sp$

So,

cost price of painting with gain% =

$\frac{100}{100 + 20} \times 924 \: = 770$

Cost price (in case of loss) =

$\frac{100}{100 - l\%} \times sp$

So,

cost price of painting with loss% =

$\frac{100}{100 - 20} \times 924 \: = 1155$

Now,

Total SP = 924+924

= 1848

Total CP = 770+1155

= 1925

As, CP > SP, loss is there

Loss = CP - SP

= 1925 - 1848

= 77

Loss% =

$\frac{loss}{cp} \times 100$

$\frac{77}{1925} \times 100 = 4\%$

Answer:

Loss of 4%
