Question

By selling an article for Rs.900, a person lost 10%. Find the C.P of the article

Answer 1

Answer:

₹1000

Step-by-step explanation:

let c.p be =x

900= x- 10x/100

900= 100x -10x /100

900=90x/100

9000=9x

x=1000

hence C.P is = ₹1000

Answer 2

Let 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
