- lets make this into again a simple thing :D ..lets rock and roll
now at present instead of ages ratios are given..so we take 4x and 3x
and after 6 years arun age is 26 ... so [present age + 6 = 26](according to question)
and so present age of arun = 4x which gives
4x + 6 = 26
solving x we get 5
question is for deepak age and deepak's present age is 3x and substituting x in 3x = 3(5) = 15
so answer is 15 years option B.15 for sure!! whenever u feel u did not understand anything just write down the given data...and try to get the answer...thats the secret of maths :D - 12 years agoHelpfull: Yes(4) No(2)
- Ans. B. 15 years
Solution:
As the ratio between the present ages of Arun and Deepak is 4 : 3, So
Deepak's Present age = (3/4)of Arun's Present age
Arun's Present age = (4/3) of Deepak's Present age
After 6 years, Arun's age will be 26 years, so
Arun's Present age = 26 - 6 = 20 years
Thus Deepak's Present age = (3/4)*20 = 15 years
Hence Ans. is B. 15 years - 12 years agoHelpfull: Yes(0) No(3)
- arun's age now= 26 yrs
arun's age before 6 yrs = 20 yrs
age of Deeoak now = 20*3/4 + 6 = 15+6= 21 yrs - 12 years agoHelpfull: Yes(0) No(2)
- arun's age now= 26 yrs
arun's age before 6 yrs = 20 yrs
age of Deeoak now = 20*3/4 = 15 yrs - 12 years agoHelpfull: Yes(0) No(2)
- At present the age of Arun is 26 then before 6 year the age of Arun is 20 years.
Let the age of Deepak is x. then 20:x= 4:3 ==> x=15
after 6 years the age of Deepak is 21 years. - 12 years agoHelpfull: Yes(0) No(1)
- After 6 years, Arun's Age will be 26. Therefore, present age of Arun is 20 Years. Ratio of arun's & deepak's age is 4:3. Hence deepak's present age is 15 years.

- Let A is the present age of Arun and D is the present age of Deepak.
Given,After 6 years, Arun's age will be 26 years.
then A+6=26
A=20 years. Arun's present age is 20 years.
The ratio of the present age of Arun is 4x=20
x=5,
then the present age of Deepak is 3x=3(5)=15 years - 12 years agoHelpfull: Yes(0) No(1)
