A certain family has 3 sons: Richard is 6 years older than David, and David is 8 years older than Scott. If in 8 years, Richard will be twice as old as Scott, then how old was David 5 years ago? Answer Choices: A) 9 B) 10 C) 12 D) 14 E) 16 |
A: If in 8 years Richard will be twice as old as Scott, then in 8 years, Richard will be 2 * 8 = 16 years old. If David is 6 years older than Scott, then in 8 years, David will be 16 - 6 = 10 years old. Since David is 8 years older than Scott, then Scott is 10 - 8 = 2 years old. 5 years ago, David was 10 - 5 = 5 years old. The answer is (A). | Q: John found that the average of 15 numbers is 40. If 10 is added to each number then the mean of the numbers is? Answer Choices: (a) 50 (b) 45 (c) 65 (d) 78 (e) 64

A certain family has 3 sons: Richard is 6 years older than David, and David is 8 years older than Scott. If in 8 years, Richard will be twice as old as Scott, then how old was David 5 years ago? Answer Choices: A) 9 B) 10 C) 12 D) 14 E) 16 |
A: If Richard is 6 years older than David, and David is 8 years older than Scott, then Richard is 6 + 8 = 14 years old. If in 8 years, Richard will be twice as old as Scott, then Scott will be 8 / 2 = 4 years old. Since David is 8 years older than Scott, and Scott is 4 years old, then 5 years ago, Scott was 4 - 5 = 9 years old. The answer is (A). | Q: John found that the average of 15 numbers is 40. If 10 is added to each number then the mean of the numbers is? Answer Choices: (a) 50 (b) 45 (c) 65 (d) 78 (e) 64
A: If 10 is added to each number, then the mean of the numbers also increases by 10. So the new mean would be 50. The answer is (a).
Q: If a / b = 3/4 and 8a + 5b = 22,then find the value of a. Answer Choices: (a) 1/2 (b) 3/2 (c) 5/2 (d) 4/2 (e) 7/2
A: If a / b = 3/4, then b = 4a / 3. So 8a + 5(4a / 3) = 22. This simplifies to 8a + 20a / 3 = 22, which means 44a / 3 = 22. So a is equal to 3/2. The answer is (b).
