Question

a shopkeeper sold an article for 1100 at a loss of 12%find it's cp and also the loss​

Answer 1

Step-by-step explanation:

$sp = 1100 \\ loss\% = 12 \\ cp = x \\ loss\% = \frac{x - 1100}{x} \times 100 \\ \frac{12}{100} \times x = x - 1100 \\ 1100 = x - 0.12x \\ 0.88x = 1100 \\ x = \frac{1100}{0.88} \\ x = 1250 \\ cp = 1250 \\ loss = cp - sp\\ loss = 1250 - 1100 = 150$
