Question

the cost of an article was rs 15500 . rs 450 were spent on its repair if it is sold for a profit of 15 percent find the selling price of the article

Answer 1

c.p = r s 15500, amount for repair = 450
total c.p = 15500 + 450 = 15950
profit percent = 15

s.p = ( 100 + p)/100 *c p
= ( 115/100)*15950
= 11.5 * 1595
= 18342.5

Answer 2

Answer:

$cost \: price \: of \: aticle \: = rs. \:15500 \: \\ cost \: of \: repair \: = rs.450 \\ total \: cost \: of \: article \: = 15\% \: \\ profit \: (rs.) = \frac{15}{100} \times 15950 = 2392.5 \\ selling \: price \: = cost \: price + profit \: \\ selling \: price \: = 15905 + 2392.5 = rs.18342.5$
