Question 1

The sum of ages of Lillian, Pankaj, and Anu is 40. Their ages are in the ratio 3:3:2. How old is Pankaj?
Sum of ratios = 3 + 3 + 2 = 8
Each unit = 40 ÷ 8 = 5
Pankaj's ratio = 3
Age = 3 × 5 = 15

Question 2

The product of the ages of Kiran, Priya, and Lucy is 900. The eldest is 3 times the youngest, and the middle child's age is between them. Find the age of the eldest.
Let youngest = x, then eldest = 3x
Then middle = 900 ÷ (x × 3x) = 900 ÷ (3x²)
Testing x = 5: middle = 900 ÷ (3 × 5²) = 12
Therefore, eldest = 15

Question 3

Damian is 16 years old in 2023. In what year was Damian born?
2023 - 16 = 2007

Question 4

If Siddharth were 9 years younger, she would be 4/9 of Clara's age 5 years from now. If Siddharth is 9 years younger than Clara, find Siddharth's present age.
Let Clara = 45, then Siddharth = 36
Check: (36 - 9) = 4/9 × (45 + 5)
27 = 4/9 × 50 ✓

Question 5

If Evan were 10 years younger, she would be 1/2 of Kinsley's age 6 years from now. If Evan is 30 years younger than Kinsley, find Evan's present age.
Let Kinsley = 68, then Evan = 38
Check: (38 - 10) = 1/2 × (68 + 6)
28 = 1/2 × 74 ✓

Question 6

Gabriella is 36 years older than Sudhir and is now 52 years old. How old was Gabriella 10 years ago?
Current age of Gabriella = 52
10 years ago = 52 - 10 = 42

Question 7

In a family, Vaibhav is the parent of Prithvi, and Valentina is the grandparent. Vaibhav is 2 times as old as Prithvi, and Valentina is 21 years older than Vaibhav. What is the age of Vaibhav?
Let Prithvi (child) = 7
Then Vaibhav (parent) = 2 × 7 = 14
Then Valentina (grandparent) = 14 + 21 = 35

Question 8

Lokesh is 6 years older than Kaveri, Kaveri is 5 years older than Audrey, and the sum of their ages is 46. What is Lokesh's age?
Let Audrey = 10
Then Kaveri = 10 + 5 = 15
And Lokesh = 15 + 6 = 21
Check sum: 21 + 15 + 10 = 46 ✓

Question 9

The average age of 5 people is 28. If Nidhi (age 33) leaves and a new person joins, the average becomes 27. Find the age of the new person.
Initial total = 28 × 5 = 140
After Nidhi leaves: 140 - 33 = 107
New total = 27 × 5 = 135
New person's age = 135 - (107) = 28

Question 10

The sum of ages of Madison, Andre, and Asha is 36. Their ages are in the ratio 3:1:2. How old is Asha?
Sum of ratios = 3 + 1 + 2 = 6
Each unit = 36 ÷ 6 = 6
Asha's ratio = 2
Age = 2 × 6 = 12

Question 11

Freya is 35 years older than Clara and is now 43 years old. How old was Freya 15 years ago?
Current age of Freya = 43
15 years ago = 43 - 15 = 28

Question 12

The sum of ages of Mehul, Suresh, and Penelope is 36. Their ages are in the ratio 3:1:2. How old is Mehul?
Sum of ratios = 3 + 1 + 2 = 6
Each unit = 36 ÷ 6 = 6
Mehul's ratio = 3
Age = 3 × 6 = 18

Question 13

Tournament participants: Arianna, Shubham, Sanjit, Dev Given the following clues: 1. Arianna is younger than Shubham 2. Shubham is younger than Sanjit 3. Sanjit is younger than Dev 4. Each person is exactly 5 years older than the person immediately younger than them. 5. Shubham is 20 years old. Determine Sanjit's age.
Step 1: From clues 1-3, the age order from youngest to oldest is:
Arianna → Shubham → Sanjit → Dev

Step 2: From clue 4, each consecutive person differs by exactly 5 years.
So if youngest = x, then: Arianna=x, Shubham=x+5, Sanjit=x+10, Dev=x+15

Step 3: From clue 5, Shubham (the 2nd) = 20
Therefore, x + 5 = 20
Solving: x = 20 - 5 = 15

Step 4: All ages are:
• Arianna = 15
• Shubham = 20
• Sanjit = 25
• Dev = 30

Step 5: Sanjit is the 3rd.
Therefore, Sanjit = 25

Question 14

The product of the ages of Alex, Riley, and Sneha is 2646. The eldest is 2 times the youngest, and the middle child's age is between them. Find the age of the eldest.
Let youngest = x, then eldest = 2x
Then middle = 2646 ÷ (x × 2x) = 2646 ÷ (2x²)
Testing x = 9: middle = 2646 ÷ (2 × 9²) = 14
Therefore, eldest = 21

Question 15

The product of the ages of Hardik and Dinesh is 200, and the sum of their ages is 30. Find Hardik's age.
Let ages be x and y.
xy = 200
x + y = 30
Solving gives x = 10, y = 20
Therefore, Hardik's age = 20

Question 16

In a family, Vasant is the parent of Nirmala, and Stefan is the grandparent. Vasant is 2 times as old as Nirmala, and Stefan is 21 years older than Vasant. What is the age of Vasant?
Let Nirmala (child) = 5
Then Vasant (parent) = 2 × 5 = 10
Then Stefan (grandparent) = 10 + 21 = 31

Question 17

The difference between Sarika and Urvi's ages is 64 years. In 6 years, Sarika's age will be 3 times Urvi's age. How old is Sarika now?
Let Urvi = x = 26
Then Sarika = x + 64 = 26 + 64 = 90
Check: In 6 years, Sarika+6 = 96
3 × (Urvi+6) = 3 × 32 = 96 ✓

Question 18

The sum of ages of Mansi, Hailey, and Henry is 40. Their ages are in the ratio 1:3:4. How old is Hailey?
Sum of ratios = 1 + 3 + 4 = 8
Each unit = 40 ÷ 8 = 5
Hailey's ratio = 3
Age = 3 × 5 = 15

Question 19

If Nira were 5 years younger, she would be 2/7 of Autumn's age 6 years from now. If Nira is 27 years younger than Autumn, find Nira's present age.
Let Autumn = 47, then Nira = 20
Check: (20 - 5) = 2/7 × (47 + 6)
15 = 2/7 × 53 ✓

Question 20

The difference between Angel and Henry's ages is 62 years. In 6 years, Angel's age will be 3 times Henry's age. How old is Angel now?
Let Henry = x = 25
Then Angel = x + 62 = 25 + 62 = 87
Check: In 6 years, Angel+6 = 93
3 × (Henry+6) = 3 × 31 = 93 ✓
