Answer 2

Step-by-step explanation:

25.038

Step-by-step explanation:

price of 100 pens = 500 3/5 or 500.60

price of 1 pen = 500.6/100 = (500/100)+(0.6/100)

= 5+0.006

=5.006

price of 3 pens = 3*5.006 = 15.018 ---------------- equation(a)

price of 50 pencils = 100 1/5 or 100.2

price of 5 pencils = 100.2/10

= (100/10)+(0.2/10)

= 10+0.02

= 10.02 -------------------equation (b)

price of 3 pens and 5 pencils = equation(a) + equation(b)

=15.018+10.02

= 25.038
