At present, the ratio between the ages of Arun and Deepak is 4 : 3. After 6 years, Arun's age will be 26 years. What is the age of Deepak at present ?

 [A]. 12 years [B]. 15 years [C]. 19 and half [D]. 21 years

Explanation:

Let the present ages of Arun and Deepak be 4x years and 3x years respectively. Then,

4x + 6 = 26       4x = 20

x = 5.

Deepak's age = 3x = 15 years.

Read problem carefully, 2nd statement is very imp. as per 2nd statement arun's current age is=(26-6)=20 yrs now 1st statement , ratio of age 4:3 4 is for arun age therefore 20/4=5 now deepak current age as per ratio 5*3=15 year Have nice day!

 Naveen Kumar said: (Sat, Jul 9, 2011 12:55:27 AM) Hi friends...Here is a simple method to solve this problem... Let arun age be x and deepak age be y The ratio of ages are x/y = 4/3... from the above equation we can write. x=4y/3......(1) given that after 6 years arun age will be 26 years.. x+6 = 26.... 4y/3 + 6 = 26. 4y/3 = 20. 4y = 60. y = 15. Hence,deepak age is 15 years.. susbstitute the x value from eq (1).

 Aman said: (Tue, Aug 23, 2011 02:36:49 PM) Well said Naveen. Your's is a better method.

 Arif Ibrahim said: (Sun, Sep 4, 2011 01:28:25 PM) Well method Naveen and it's easy too.

 Sai said: (Wed, Dec 7, 2011 08:06:50 PM) Age =x Ration of arun and deepak is 4:3 After 6 year arun age wil be 26 So, 4x+6=26 = x=5 Deepak age wil be =3x=15

 Aish said: (Tue, Mar 6, 2012 08:47:14 PM) Anyone please explain this problem. Last year pandit was thrice his sister's age. Next year he is only twice her age. After 5 years what is pandit's age.

 Shilpa said: (Wed, Apr 25, 2012 07:20:41 PM) Arun age 4x+6=26----------->1 4 is ratio x is variable n 26 is his present age Deepak age y=3x------------>2 Here y is taken for just to equate, x is variable Now simplify eq 1 4x=26-6 ==> x=5 Sub x value in eq 2 y=3*5 (y is deepak's age) y=15 That's it:)

 Sai said: (Thu, Jul 19, 2012 03:05:09 PM) Given that Arun and Deepak age are in the ratio 4x:3x. Arun age after 6 years is 4x+6=26. X=5. 3x=15.

 Archana Tripathi said: (Wed, Jan 9, 2013 09:50:39 PM) Let arun age is x and deepak age is y. According to question, x/y= 4/3 -- (1) x+6=26 x=20. From(1) y=(3/4)*x Put x=20 y=(3/4)*20 y=15 So deepak age is 15 years.
