$\large\huge{\fcolorbox{blue}{golden}{\red{Answer}}}$

Selling Price of one iron= Rs.960

Gain 20%

$cost \: price = 960 \times \frac{100}{120} = 800rs$

Selling Price of another iron = Rs.960

Loss 20%

$cost \: price \: = 960 \times \frac{100}{80} = rs.1200$

Cost prices of two irons = Rs. 800 + 1200 = Rs.2000

$selling \: price \: of \: two \: irons = 2 \times 960 = rs.1920$

Loss Rs 2000 - 1920 =Rs. 80

✿It is loss✿

✿Percantage:-

$loss\% = \frac{80}{100} \times 100 = 4 \%$

✿Points:-

• selling price is amount of the things that is sold.
• Cost price is amount of the thing that is bought by consumers.
