Question

the sp of 12 pens is equal to the cp of 15 pens . find the gain percent​

Answer 1

Answer:

let the c.p. of each pen be ,rs.1

Step-by-step explanation:

cp of 12 pens=rs.12

given that,

sp of 12 pens =cp of 15 pens

=rs.15

here,

CP<SP

so profit. =rs(15-12)

=rs.3

Hence profit%=(3/12*100)%

=(100/4)%

=25%

Answer 2

Answer: 20%

Step-by-step explanation:

The SP of 12pens = 12

The CP of 15 pens = 15

Gain = 15 - 12 = 3 units

Gain percent = 3/ 15 × 100 = 20% .

Answer : 20%
