Please check your question. The man may have spent Rs. 740 instead of 750 or some other value may be wrong. Taking spent money as Rs. 740, here's the answer:
Let the no. of notebooks by x and no. of pens be y.
Cost of each notebook = Rs. 110
Cost of each pen = Rs. 150/3 = Rs. 50
[tex]x+y=10 =\ \textgreater \ x=10-y \\ 110 x +50y=740 \\ 110(10-y)+50y=740 \\ 1100-110y+50y=740 \\ 60y=360 \\ y = \frac{360}{60} =6[/tex]
No. of notebooks, x = 10 - y = 10 - 6 = 4
No. of pens, y = 6
