The correct option is C 400 dollars
Logan has 600 dollars.
Money spent on stationery = 30 dollars
Money spent in buying books = 160 dollars
Total money spent = 30 + 160 = 190 dollars
Money left with him = 600 – 190
= 410
In this number, the tens digit is 1. Since it is not more than 5, the number should be rounded down.
Therefore, when we round the number to the nearest hundred, we get 400.
Hence, the money left with him = 400 dollars
