The correct option is A 960, 270
In the number 690, we have 6 at the hundreds' place and 0 at the ones' place. Additionally, in 960, we have 9 at the hundreds' place and 0 at the ones' place.
When we compare two numbers, we start from the left. So comparing 690 and 960 we start from the hundreds' place. In 690, 6 is at the hundreds' place. In 960, 9 is at the hundreds' place. Clearly, 9 is greater than 6, or 9 > 6.
Thus, it can be concluded that 690< 960. Finding the difference between them,
960 - 690 = 270.
