Question

Which of the following pair of numbers add to give a number greater than 500?

• A. 195 and 181
• B. 292 and 332
• C. 112 and 86
• D. 294 and 86

Answer 1

The correct option is B 292 and 332

195 and 181 are both close to 200.
Thus, the sum $195+181$ is best estimated by the sum $200+200=400,$ which is less than 500.

Similarly, we can see that the sum of 112 and 86 is best estimated by $100+100=200,$ which is less than 500.

The sum of 294 and 86 can be estimated by $300+100=400,$ less than 500.

But, the sum $292+332$ is estimated by $300+300=600,$ which is greater than 500.
