Question 5: In a family of six (P, Q, R, S, T, U), there are two married couples. Q is a doctor and the father of T. U is the grandfather of R and is a contractor. S is the grandmother of T and is a housewife. There is one doctor, one contractor, one nurse, one housewife, and two students in the family. Which of the following is definitely a married couple?
- Q and R
- U and T
- P and R
- U and S (Correct answer)
Correct answer: U and S
S is the grandmother of T, and Q is the father of T. This means S is the mother of Q. U is the grandfather of R. Since S is a grandmother and U is a grandfather, and there are two married couples, it is highly likely they are a couple. U is the grandfather of R and S is the grandmother of T, and with Q being the father of T, U and S are the parents of Q, making them a married couple.
Question 6: A woman says, "If you reverse my age, the figure represents my husband's age. He is, of course, senior to me and the difference between our ages is one-eleventh of their sum." What is the woman's age?
- 23
- 34
- 45 (Correct answer)
- 56
Correct answer: 45
Let the woman's age be 10x + y and the husband's age be 10y + x. According to the problem, (10y + x) - (10x + y) = (1/11) * ((10y + x) + (10x + y)). This simplifies to 9y - 9x = (1/11) * (11x + 11y), which further simplifies to 9(y - x) = x + y. Testing the options, if the woman's age is 45 (x=4, y=5), her husband's age is 54. The difference is 9, and the sum is 99. 9 is one-eleventh of 99. This satisfies the condition.
