Answer 2

Answer:

ANSWER...Rs 520

Per/pen=Rs 65

Step-by-step explanation:

C.P. of 10 pen= Rs.500

C.P. of 1 pen:

$\frac{500}{10} \\ = 50$

.°. C.P. of 1=Rs.50

S.P. of 1 pen=Rs.40

S.P. of 2 pen= 40+40=Rs.80

Gain=20 percent

Means now amount after gain:

$= 500 + (500 \times \frac{20}{100} ) \\ = 500 + 100 \\ = 600$

Now, S.P. of 8 pens= 600-80

=Rs 520

Price of 1 pen=520/8

=Rs 65

Therefore, At rs 65 each pen should sell to gain 20 percent....
