Question 1

A is 3 years younger than B. The sum of their ages after 3 years will be 55. Find A's present age.
Let A=23, B=26. After 3 years: A=26, B=29, sum=55. Therefore A = 23

Question 2

The sum of ages of all family members is 80 and their average age is 20. How many members are there in the family?
number = total / average = 80 / 20 = 4
member_count

Question 3

10 years ago, A was half as old as B. In 5 years, what will be the age difference between B and A?
10 years ago: A was 17, B was 24. Check: 17 = ½ × 24 ✓
Present ages: A = 27, B = 34
In 5 years: A = 32, B = 39
Age difference = |39 - 32| = 7
(Age difference stays constant over time = B - A = 7)

Question 6

Ratio of ages of Saurabh to Ava is 3:2, and the difference is 5. How old is Saurabh?
Let Saurabh = 3x, Ava = 2x
Difference = 3x - 2x = 1x = 5
Therefore x = 5 ÷ 1 = 5
Saurabh = 3 × 5 = 15
ratio

Question 7

In 7 years, Riya will be 3 times as old as Suman will be then. Suman's present age is 12. What is Riya's present age?
Riya+7=3*(12+7) -> Riya=3*(12+7)-7=50
multiple

Question 8

Present ages of Lucia, Pallavi, Julia are in ratio 3:4:5. Sum of ages is 120. Find Lucia's age.
Let ages be 3x, 4x, 5x. Sum = 12x = 120, so x = 10. Lucia = 3×10 = 30

Question 9

The sum of ages of all family members is 145 and their average age is 29. How many members are there in the family?
number = total / average = 145 / 29 = 5

Question 11

Daniel is 20% younger than Jivika. If Jivika is 33 years, how old is Daniel?
Daniel = 33 - (20% of 33) = 33 - 6 = 27

Question 12

Sum of A and B's ages is 53. After 7 years, A will be 3 times as old as B. What is the maximum possible age of A now?
A + B = 53, (A+7) = 3*(B+7) → A = 43.2 → max A = 43
