1. **Stating the problem:** We have three statements in an advertisement: i. There are three statements in this ad. ii. Two of them are not true. iii. The average increase in IQ scores of people who learn this game is more than 20 points. 2. **Analyzing the statements:** - Statement (i) says there are three statements, which is true. - Statement (ii) says two of the statements are not true. 3. **Checking consistency:** - If (ii) is true, then exactly two statements are false. - Since (i) is true, and (ii) is true, then (iii) must be false to satisfy (ii). 4. **Conclusion:** - Statement (iii) is false. - Therefore, the average increase in IQ scores is not more than 20 points. This is a logical puzzle rather than a mathematical formula problem, but the reasoning shows that (iii) cannot be true if (i) and (ii) are true.
