Three markers and one pen cost Rs. 340. Four markers and two pens cost Rs. 560. What is the price of one pen?
- Rs. 120
- Rs. 140
- Rs. 160
- Rs. 180
Explanation
Let the price of one marker = M
Let the price of one pen = P
3M + P = 340 ...(1)
4M + 2P = 560 ...(2)
Divide equation (2) by 2:
2M + P = 280 ...(3)
Subtract equation (3) from equation (1):
(3M + P) − (2M + P) = 340 − 280
M = 60
Substitute M = 60 into equation (1):
3(60) + P = 340
180 + P = 340
P = 340 − 180
Rs. 160
