Question

A pen costs 7 times as that of a pencil .If raju buys 3 pencils and 2 pens and pays rs 34what is tge cost of pen and pencil

Answer 1

Answer:

Let the cost of pencil of be x ∴ the cost of the pen = 7x 2 pens = 2 ... If Raju buys 3 pencil and 2 pens and pays Rs34, what is the cost ... cost of pencils raju buys = 3x

Answer 2

Step-by-step explanation:

cost of pencil = Rs.x

cost of pen = Rs. 7x

Total cost of the pencils bought = Rs. 3 X x = Rs.3x

Total cost of the pens bought = Rs. 2 X (7x) = Rs. 14x

Total cost of all = Rs.34

Solution:

3x + 14x = 34

17x = 34

x = 34/14

x = Rs.2

Thus,

Cost of a pencil = Rs.2

Cost of a pen = Rs. 7 X 2 = Rs. 14
