Question 1

In a family, Nevaeh : Narendra = 5:4 and Narendra : Kumud = 4:1. The sum of their ages is 50. Find Narendra's age.
Let common ratio for Narendra be 4
Then Nevaeh:Narendra:Kumud = 5:4:1
Sum of ratios = 10
Each unit = 50 ÷ 10 = 5
Narendra's age = 4 × 5 = 20

Question 2

Four people: Prateek, George, Arlo, Samuel Given: 1. The sum of all four ages is 132 2. Prateek + George = 46 3. Samuel is 10 years older than Arlo 4. Samuel is 48 years old Find George's age.
Step 1: From clue 4, Samuel = 48

Step 2: Using clue 2, we can find the other person in that pair

Step 3: Using clue 3 and clue 1, we can determine all ages

Step 4: Therefore, George = 29

Complete ages: Prateek=17, George=29, Arlo=38, Samuel=48

Question 3

The product of the ages of Addison, Shivam, and Pankaj is 490. 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 = 490 ÷ (x × 2x) = 490 ÷ (2x²)
Testing x = 5: middle = 490 ÷ (2 × 5²) = 7
Therefore, eldest = 14
product

Question 4

Currently, Jahnavi is 2/3 of Evelyn's age. After 6 years, Jahnavi will be 3/4 of Evelyn's age. Find Jahnavi's present age.
Let Evelyn = x, then Jahnavi = 2/3x
After 6 years: 2/3x + 6 = 3/4(x + 6)
Solving gives x = 18, so Jahnavi = 12

Question 5

Currently, Sanyam is 1/2 of Tristan's age. After 9 years, Sanyam will be 2/3 of Tristan's age. Find Sanyam's present age.
Let Tristan = x, then Sanyam = 1/2x
After 9 years: 1/2x + 9 = 2/3(x + 9)
Solving gives x = 36, so Sanyam = 18
fraction, time-change

Question 6

Currently, Shivani is 2/5 of Giselle's age. After 10 years, Shivani will be 1/2 of Giselle's age. Find Shivani's present age.
Let Giselle = x, then Shivani = 2/5x
After 10 years: 2/5x + 10 = 1/2(x + 10)
Solving gives x = 50, so Shivani = 20
fraction, time-change

Question 7

The average age of a family of 7 members (Hugo, Mamta, Skylar, Niyati, Ishwar, Rohan, Gunjan) is 20.7 years. If Ishwar (age 43) leaves the family, what will be the new average age?
Total age = 20.7 × 7 = 145
After Ishwar leaves: 145 - 43 = 102
New average = 102 ÷ 6 = 17

Question 8

Omar and Shiva are twins. If Omar is 12 years old now, how old was Shiva 7 years ago?
Twins have the same age. 7 years ago, both were 12 - 7 = 5

Question 9

The product of the ages of Emma and Willow is 546, and the difference between their ages is 5. Find Emma's age.
Let ages be x and y.
xy = 546
x - y = 5
Solving gives x = 21, y = 26
Therefore, Emma's age = 26

Question 10

Vikram is twice as old as Meena was when Yashaswi was as old as Vikram is now. If Yashaswi is currently 33 years old, find Vikram's age.
When Yashaswi was 38 years old, that was 5 years ago
At that time, Meena was 19
Now Vikram = 2 × 19 = 38 ✓

Question 11

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

Question 12

The difference between Rakhi and Kaveri's ages is 30 years. In 3 years, Rakhi's age will be 2 times Kaveri's age. How old is Rakhi now?
Let Kaveri = x = 27
Then Rakhi = x + 30 = 27 + 30 = 57
Check: In 3 years, Rakhi+3 = 60
2 × (Kaveri+3) = 2 × 30 = 60 ✓

Question 13

Nimesh is 18 years old and Nisha is 22 years old. What will be their combined age after 11 years?
Nimesh will be 18 + 11 = 29
Nisha will be 22 + 11 = 33
Combined = 29 + 33 = 62

Question 14

Kiran is twice as old as Alok was 7 years ago. The difference between their ages is 19 years. How old is Kiran?
Let Alok's current age = x
Then 7 years ago, Alok was (x - 7)
Kiran = 2(x - 7) = 2x - 14
Difference: Kiran - x = (2x - 14) - x = x - 14
Given difference = 19
So x - 14 = 19 → x = 33 = 33
Then Kiran = 2(33 - 7) = 52

Question 15

If Bryson were 9 years younger, she would be 1/2 of George's age 5 years from now. If Bryson is 26 years younger than George, find Bryson's present age.
Let George = 60, then Bryson = 34
Check: (34 - 9) = 1/2 × (60 + 5)
25 = 1/2 × 65 ✓

Question 16

The average age of a family of 6 members (Patrick, Satish, Kaushal, Lydia, Jatin, Kunal) is 25.0 years. If Kaushal (age 20) leaves the family, what will be the new average age?
Total age = 25.0 × 6 = 150
After Kaushal leaves: 150 - 20 = 130
New average = 130 ÷ 5 = 26

Question 17

Finn is 4 times as old as Kaylee. 4 years ago, the sum of their ages was 102. How old is Kaylee now?
Let Kaylee = x, then Finn = 4x
4 years ago: (4x - 4) + (x - 4) = 102
(4+1)x - 8 = 102
(5)x = 110
x = 22

Question 18

Nidhi is twice as old as Tanu was when Prateek was as old as Nidhi is now. If Prateek is currently 47 years old, find Nidhi's age.
When Prateek was 54 years old, that was 7 years ago
At that time, Tanu was 27
Now Nidhi = 2 × 27 = 54 ✓

Question 19

The product of the ages of Subhash and Payal is 288, and the difference between their ages is 2. Find Subhash's age.
Let ages be x and y.
xy = 288
x - y = 2
Solving gives x = 16, y = 18
Therefore, Subhash's age = 18

Question 20

In a family, Everett : Stella = 8:3 and Stella : Sagar = 4:1. The sum of their ages is 188. Find Stella's age.
Let common ratio for Stella be 12
Then Everett:Stella:Sagar = 32:12:3
Sum of ratios = 47
Each unit = 188 ÷ 47 = 4
Stella's age = 12 × 4 = 48
