Detailed Solution
Download Solution PDFLet,
Price of one pen = x
Price of one notebook = y
Given:
1) Mohit bought 3 pens and 6 notebooks by paying an amount of Rs. 180
=> 3x + 6y = 180
=> 3x = 180 – 6y
=> x = (180 – 6y) ÷ 3
=> x = 60 – 2y --------------- (i)
2) Sudesh bought 5 pens and 2 notebooks by paying an amount of Rs. 116
=> 5x + 2y = 116
Putting the value of x from eq (i)
=> 5(60 – 2y) + 2y = 116
=> 300 – 10y + 2y = 116
=> 300 – 116 = 10y – 2y
=> 8y = 184
=> y = 23
Mohit spend on buying 6 notebooks
=> 6y = 6 × 23 = 138
Hence, Mohit spend “Rs. 138” on buying notebooks.Last updated on Jun 13, 2025
