Question

The age of Rohan is 3 times the age of Sohan. After 10 years, Rohan's age will be twice the age of Sohan. Find their present ages.​

Answer 1

Answer:

rohan in 30 and sohan is 10

Step-by-step explanation:

working on the question - rohan is 3 times of sohan
=>  R = 3S---------1)
second equation comes out to be
=> R+10 = 2(S+10) {after 10 years}---------2)
=> R+10 = 2S + 20
=> R = 2S + 10  -------- 3)

putting the value in eq1
=> 2S +10 = 3S
=> 10 = S

and rohan is 3 times of sohan
=> 10x3 = 30

hence rohan is 30 and sohan is 10


HOPE IT HELPS GOOD DAY :D

Answer 2

Step-by-step explanation:

Correct option is A)

Let the age of Sohan be x years

∴ Age of Mohan =(x+4)years

Sum of their ages =54

x+(x+4)=54

2x+4=54

2x=50⇒x=25

Age of Sohan =25years

Age of Mohan =x+4=25+4=29years
