Question

Age of rohit is 5 more than twice the age of pradeep .6 year ago age of pradeep was 1/3 of rohits age. Find their age .

Answer 1

let the age of Rohit is 'r' and age of Pradeep is 'p'.

according to the conditions in the question,

r=2p+5
therefore, r - 2p=5......... (1)

p - 6 =(1÷3)(r -6)
therefore. , 3p - 12= r .......... (2)
by substituting r =3p -12 in the first equation we get,
(3p - 12) -2p = 5
therefore, 3p- 12- 2p = 5
p -12 = 5
p = 17
latest substitute p = 17 in the first equation,
r - 2(17) = 5
therefore, r - 34 =5
r = 34 + 5
r = 39

therefore age of Rohit is 39 and the age of Pradeep is 17.

I think it is a satisfactory answer , do you?

Answer 2

Answer: hope its help to u

Step-by-step explanation:

let the age of Rohit is 'r' and age of Pradeep is 'p'.

according to the conditions in the question,

r=2p+5

therefore, r - 2p=5... (1)

p - 6 =(1÷3)(r -6)

therefore. , 3p - 12= r .. (2)

by substituting r =3p -12 in the first equation we get,

(3p - 12) -2p = 5

therefore, 3p- 12- 2p = 5

p -12 = 5

p = 17

latest substitute p = 17 in the first equation,

r - 2(17) = 5

therefore, r - 34 =5

r = 34 + 5

r = 39

therefore age of Rohit is 39 and the age of Pradeep 7
