InfyTQ Problems on Ages Quiz 2

let Deepak’s age be x
If Deepak’s age is x, then Dipti’s age will be 3x.
Rani is 4 years younger than Dipti, so her age will be 3x-4
Given, x+3x+3x-4 = 66
7x = 70
x = 10
Therefore, Dipti’s age will be 3*10 = 30 years

Let us take Aditi’s age as x, Arnav’s age as y, and Aashay’s age as z.
Given, (x+y) = 14 + (y+z)
(x+y) - (y+z) = 14
x-y = 14 years
The difference between Aditi and Aashay’s age is 14 years.

Let us assume M’s age as x.
Then, Z’s present age will be = x+6
After 7 years = x+6+7 = 3(x-7)
X+13 = 3x – 21
2x = 34
X = 17
The present age of M is 17 years.

Let Radha’s age be 7x and Shyam’s age be 4x
Given, product of their ages : 7x*4x = 448
28 x² = 448
x² = 16
x = 4
Radha’s age after 3 years will be 7x + 3 = 7*4+3 = 31 years
Shyam’s age after 3 years will be 4x+3 = 4*4+3 = 19 years

Let Rama’s daughter’s and son’s age be x and (x-50) respectively.
Given, four years ago their age will be (50 - x) - 4= 2(x - 4)
46 - x = 2x – 8
3x = 54
x = 18.
Rama’s daughter’s age is 18 years.

Ronit’s present age is 18+1 = 19 years.
5 years later, Ronak\'s uncle will be three times of Ronit\'s age = 19*3 = 57 years.
Ronak’s uncle’s present age is 57-3 = 54 years.
3 years later Ronak’s uncle’s age will be 57 years.
Ronak\'s present age is 57/6 = 9.5 years.

Let Raghav’s age be x, and his brother raj’s age be x+12
so, x / x+12=4/5
5x = 4x + 48
X= 48
Raghav’s age is 48 years.

Lakhan’s present age is 15 years.
Hence, 3years back, his age was 12 years
Therefore, Rashmi’s age will be (5/2*12) = 30 years
Rashmi’s present age is 30 + 3 = 33 years.

Let Shivam’s age when he got married be x
Given, x + 6 = 5/4 x
4x +24 = 5x
x = 24

Shivam’s age when he got married was 24 years
Shivam’s present age is 24+6 = 30years
His brother is 6 years younger to him = 30 - 6 = 24 years.

Let, the sum of Ravi’s son’s present age be x.
Then, Ravi’s age will be 3x .
Given, (3x + 4) = 2 (x +4+4)
3x + 4= 2x + 16
x = 12
Therefore, Ravi’s current age =12*3 = 36 years.
