ExplanationShow

The correct answer is $161$ . For a number to be $40%$ greater than $115$ , it follows that the number is $(100% of 115) + (40% of 115)$ , which can be written as $\frac{100}{100} (115) + \frac{40}{100} (115)$ . This expression is equivalent to $1 (115) + 0.4 (115)$ , or $1.4 (115)$ , which is equal to $161$ . Therefore, $161$ is $40%$ greater than $115$ .
