At present, the ratio between the ages of Arun and Deepak is 3 : 2. After 13 years, Arun's age will be 34 years. What would be the age of Deepak after 8 years from now ?

OPtion

1) 14 Years
2) 15 Years
3) 17 Years
4) 18 Years
5) 19 Years
6) 20 Years
7) 21 Years
8) 22 Years
9) 23 Years
10) None of these

Solution

Let the present ages of Arun and Deepak be 3x years and 2x years respectively. Then,

3x + 13 = 34 => 3x = 21
x = 7
Deepak's present age = 2x = 14 years.
Deepak's Age after 8 years = 14 + 8 = 22 Years

Correct Option: 8 Best Solution (11)

G.S.Kantharao   8 years AGO

Let the ages are 3x,2x
After 13 years Arun =3x + 13 =34
3x = 34 -13 =21
x =21/3 = 7yrs.
After 8 yrs Deepak's age =( 2*7) + 8 = 22yrs
Hence the right option is 8.

ganesh chemanchula   8 years AGO

let arun's age be x and deepak's age be y..so x:y=3:2
x+13=34..means x=21..then y=14
Deepak's age after 8 years= 14+8=22 years

SAYAN CHATTERJEE   8 years AGO

Arun's present age being A and that of Deepak being D,
A/D= 3/2....
A+13=34
A=21..
So, D= 21*2/3
= 14
So, after 8 yrs, deepak's age will be 14+8= 22..

Option 8.

Payal   8 years AGO

Let A and D be Arun and Deepak's current age respectively.
Then
A/D=3/2 -----eq 1
A+13=34
hence A=21 years
substituting in eq 1
21/D=3/2
D=14 years
Afer 8 years deepaks age will be 14+8=22 years
hence option 8

Devendra Marghade   8 years AGO

Arun's present age= 34-13=21 years
As present ratio of age Arun/Deepak=3/2
So Deepak's age=(2/3)*Arun's Age=(2/3)*21=14 years.
Hence Deepak's age after 8 years=14+8=22 years.
