Question

What is the cost of each pen?
(i)The cost of 6 pens and 5 pencils is Rupees 36.
(ii)If the cost of each pen and each pencil is reduced by 40% then the cost of 12 pens and 10 pencils is rupees 36.

Answer 1

Answer:

1: Cost of pen =x

Cost of pencil =y

6x+5y=30

12×0.6x + 10×0.6y =36

7.2x+6y=36

Both the facts are not sufficient to find out value of x and y.
