Step-by-step explanation:
Possibilities (pens are more expensive than pencils)
So if pens are 3Rs each then 3 pens would be 9Rs
Your sum says the total is 14Rs so minus 9Rs leaves 5Rs for 5 pencils or 1Rs each
Therefore 10 pens equals 30Rs and 12 pencils equals 12Rs So new total and your answer is 42Rs.
