Question

by selling an article for 900 a person lost 10% find the co of the article​

Answer 1

Answer:

therefore the cp if an article is ₹1000

Step-by-step explanation:

sp of article = ₹900

loss %=10%

cp= 100×sp/(100-loss%)

cp=100×900/90= 100×10

=1000

Answer 2

$let \: the \: c.p \: = x \\ s.p = 900 \\ loss\% = 10\% \\ c.p = \frac{100}{100 - 10} \times 900 \\ = \frac{100}{90} \times 900 \\ = \frac{100}{1 } \times 10$

then multiply =

100×10=1000

C.p = 1000
