Answer:
1 pen cost = 20 rupee and 1 pencil cost10 rupee
so 3 pen = 3×20=60 and 4 pencil = 4 ×10 =40
of both are in bag so total amount of Money is 40+60= 100 rupees is the answer

Answer:we take pens and pencils as:
pens=p
pencils =E
Just we have to find total coast
Total cost=20×p+10×E
Let no of pens=3
Pens=4
So it's, 20×3+20×4
It become 60+40=₹100 is the total cost.
