    Miguel is 46 years old. He is 4 years older than thrice his Niko's age. Find the age of Niko.

    • Niko is 15 years old.

    • Niko is 14 years old.

    • Niko is 13 years old.

    • Niko is 10 years old.

    • Niko is 11 years old.

    Correct Answer
    A. Niko is 14 years old.
    Explanation
    The question states that Miguel is 46 years old and is 4 years older than thrice Niko's age. Let's assume Niko's age to be x. According to the given information, Miguel's age can be expressed as 3x + 4. We are told that Miguel is 46 years old, so we can set up the equation 3x + 4 = 46. Solving this equation, we find that x = 14. Therefore, Niko is 14 years old.

    Edward, Bryan and Mark are cousins.Edawrd’s age is one-third of Bryan and Mark is five years elder than Bryan. If the sum of the age of the cousins is 40, find the ages of each.

    • Edward=5 Bryan=15 Mark=20

    • Edward=2 Bryan=13 Mark=25

    • Edward=9 Bryan=14 Mark=17

    • Edward=11 Bryan=13 Mark=16

    • Edward=10 Bryan=8 Mark=22

    Correct Answer
    A. Edward=5 Bryan=15 Mark=20
    Explanation
    Edward's age is one-third of Bryan's age, so if Bryan is 15 years old, Edward would be 5 years old. Mark is five years older than Bryan, so if Bryan is 15 years old, Mark would be 20 years old. The sum of their ages is 5 + 15 + 20 = 40, which matches the given information. Therefore, the ages of Edward, Bryan, and Mark are 5, 15, and 20 respectively.

    One-half of Heather's age two years from now plus one-third of her age three years ago is twenty years. How old is she now? 

    • Heather is 36 years old.

    • Heather is 45 years old.

    • Heather is 67 years old.

    • Heather is 24 years old.

    • Heather is 56 years old.

    Correct Answer
    A. Heather is 24 years old.
    Explanation
    Let's assume Heather's current age is x. Two years from now, her age will be x + 2. Three years ago, her age was x - 3. According to the given information, (1/2)(x + 2) + (1/3)(x - 3) = 20. Simplifying this equation, we get (3x + 6 + 2x - 6)/6 = 20. Combining like terms, we have 5x/6 = 20. Multiplying both sides by 6/5, we find x = 24. Therefore, Heather is currently 24 years old.

    The sum of Ben and carol's age is 36. Nine years ago, Ben was twice as old as Carol. How old is each now?

    • Ben's age now is 19, Carol's age now is 17.

    • Ben's age now is 18, Carol's age now is 18.

    • Ben's age now is 21, Carol's age now is 15.

    • Ben's age now is 31, Carol's age now is 5.

    • Ben's age now is 23, Carol's age now is 13.

    Correct Answer
    A. Ben's age now is 21, Carol's age now is 15.
    Explanation
    Let's assume Ben's age is B and Carol's age is C. According to the given information, B + C = 36. Nine years ago, Ben's age was B - 9 and Carol's age was C - 9. It is also stated that Ben was twice as old as Carol at that time, so we can write the equation B - 9 = 2(C - 9). Solving these two equations simultaneously, we get B = 21 and C = 15. Therefore, Ben's age now is 21 and Carol's age now is 15.

    John is twice as old as his friend Peter. Peter is 5 years older than Alice. In 5 years, John will be three times as old as Alice. How old is Peter now?

    • Peter is now 10 years old.

    • Peter is now 5 years old.

    • Peter is now 45 years old.

    • Peter is now 21 years old.

    • Peter is now 3 years old.

    Correct Answer
    A. Peter is now 10 years old.
    Explanation
    John is currently twice as old as Peter.
    Peter is 5 years older than Alice, meaning if you take Peter's age and subtract 5 years, you get Alice's current age.
    In 5 years, John will be three times as old as Alice is now. Since we know John's future age relation to Alice's current age, we can set up a relationship between their ages to solve the problem.
    To find Peter's current age, we use the information that in 5 years, the difference in age between John and Alice, considering John's age as twice Peter's, reveals Peter's age relation to Alice. Knowing Peter is 5 years older than Alice and applying the condition about John's age in 5 years being three times Alice's current age allows us to calculate Peter's age. Through a series of substitutions and simplifications based on these relationships, we find that Peter is 10 years old now.

    Sam is 3 years younger than Alex and Alex is 7 years older than Mary. If the sum of their ages is 44, find each persons age.

    • Alex's age = 16 Sam's age = 15 Mary's age = 11

    • Alex's age = 14 Sam's age = 15 Mary's age = 11

    • Alex's age = 15 Sam's age = 15 Mary's age = 11

    • Alex's age = 18 Sam's age = 15 Mary's age = 11

    • Alex's age = 12 Sam's age = 14 Mary's age = 1

    Correct Answer
    A. Alex's age = 18 Sam's age = 15 Mary's age = 11
    Explanation
    Let's assume Sam's age as x. Since Sam is 3 years younger than Alex, Alex's age would be x + 3. Since Alex is 7 years older than Mary, Mary's age would be x - 4. The sum of their ages is given as 44, so we can form the equation x + (x + 3) + (x - 4) = 44. Solving this equation, we get x = 15. Therefore, Sam's age is 15, Alex's age is 18, and Mary's age is 11.
