Answer:
Let the number of notebooks be x.
Then, the number if pens = 3x.
Cost of 1 pen = 15 rupees
Cost of 1 notebook = 40 rupees
Total cost = 425 rupees
Therefore,
40x + 15(3x) = 425
40x + 45x = 425
85x = 425
x= 425/85
x=5
3x = 5 x 3 = 15
Therefore, the number of notebooks = x = 5
number of pens = 3x = 15
