D Correct answer
Explanation

Let Valerie's current age be V. Monique is 24 (M=24). When Monique was V years old (in the past, 24-V years ago), Valerie was V-(24-V) = 2V-24 years old. Monique is now twice that age: 24 = 2(2V-24). Solving: 24 = 4V-48, so 4V=72 and V=18. Valerie is 18 years old.

D Correct answer
Explanation

Let the son's current age be x. Father's current age is 5x. Three years back, son was x-3 and father was 5x-3. Since father was 24 years older than son three years back: 5x-3 = x-3+24, which gives 4x=24, so x=6. Son is currently 6, so three years from now he will be 9 years old.

The wife died at 50. The husband was 30 when they married, and she was 25, so he was 5 years older. When she died at 50, he was 55. He cried for years, then stopped, and 10 years later he died. The question asks about widower years IF he lived to 80. From age 55 to 80 is 25 years of being a widower.

The ages of a father and son add up to 66. The father's age is the son's age reversed. How old could they be? (3 possible solutions).

  1. 51 and 15

  2. 42 and 24

  3. 60 and 06

  4. 82 and 28
Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation

Let the son's age be AB (two digits), then father's age is BA. So (10A+B) + (10B+A) = 66, meaning 11(A+B) = 66, so A+B = 6. Valid pairs where father > son: (0,6), (1,5), (2,4). This gives ages 60 and 06, 51 and 15, 42 and 24. The option 82 and 28 sums to 110, not 66.

B Correct answer
Explanation

Let current age be x. If you live 15 more years, you'll be 38, so x = 38 - 15 = 23. Daughter is 10 now and was born 3 years after marriage, so marriage was 10 + 3 = 13 years ago. Current year is 2024, so marriage year = 2024 - 13 = 2011. Option D is a joke option. The math works out correctly to 2011.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Let the son's current age be x years. Then the father's current age is 3x years. After 5 years: (3x + 5) = 2.5(x + 5), which gives 3x + 5 = 2.5x + 12.5, so 0.5x = 7.5 and x = 15. The son is 15 years old now, and the father is 45 years old now. At the son's birth (15 years ago), the father's age was 45 - 15 = 30 years.
