Solution

The correct option is B 24,451, Distributive property
49 × 499
= 49 × (500 -1)
Applying distributive property, we get
= 49 × 500 - 49 × 1
Again applying distributive property, we get
= (50 - 1) × 500- 49
= 50 × 500 - 1 × 500 - 49
= 25,000 - 500 - 49
= 24,451
So, option a is the correct answer.
