Question

Three pens and five pencils together costs Rs.55. If each pen costs two times that of each pencil, find the cost of each pen and each pencil. ​

Answer 1

Answer:

Pencil  = Rs. 5, Pen = Rs. 10

Step-by-step explanation:

or, lets take the cost of pencil as x

or, 3x x 2 + 5x = Rs. 55

or, 6x + 5x = Rs. 55

or, 11x = rs. 55

or x = 55/11

or, x = Rs. 5

Cost of each pencil = Rs. 5

Cost of each pencil = Rs. 5 x 2

                                 = Rs. 10

Therefore cost of each pen is Rs. 10 and cost of each pencil if Rs. 5.
