Answers
answer:
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

Answer:
100 pens = 500 3/5
1pen = 500×3/5×100
=3 rs.
50 pencils =100 ×1/5
1 pencil = 100×1/5÷1/50
= 2/5
3 pens = 3 ×3 = 9rs.
5 pencils = 5 ×2/5 = 2 rs.
