Question

Find the cost price of an article which is sold for

Rs.2400 .The dealer makes a profit of 20 percent on the

transaction.​

Answer 1

Answer:

Let the cost price be [x]

$\boxed{ \tt{simple \: intrest = \frac{principle \times rate \: of \: intrest \times time}{?} }}$

$\rm \dfrac{x \times 20}{100} = 2400$

$\rm{x = \dfrac{2400 \times 100}{20} }$

$\rm{x = 12 0\times 10}$

$\rm{x = 1200}$
