Question

the cost of 10 pencils is Rs 500 two pens are sold at Rs 40 each at what at what price should the remaining pens be sold so as to gain 20% on the whole​

Answer 1

Answer:

2 +8 =10

2×40=80

500-80=420

=20%×500

=20×500/100

=100

total profit=100

money =500+100

=600

600-80=520

520÷8=65

therefore the remaining 8pens should be sold at a price of 65 rupees each.
