Let's C. P. =x of 6 items

so, we have to profit 20% of x

20% of x is. 2x

CP-PROFIT =SP

SP is 15

cp is x

so, x-.2x=15

. 8x=15

so, x =15/.8=18.75 is cp if we have to 20% profit

but there is ask 1 item cp so, 18.75/6=3.125 is your answer.

Answer 2

Answer:

•The cost price of 6 items is rs.15

• So, cost of one item =

15 ÷ 6 = rs.2.5

$sp = { \frac{(100 + gain\%)}{100} } \times cp$

$= > \frac{(100 + 20)}{100} \times 2.5$

$= > \frac{120}{100} \times2 .5$

$= >rs. \: 3$
