​

Answer 1

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
