Two years ago, Appu's age was Six times Ammu's age .After Four years, it would just be thrice. What are their ages now?
please I want correct answer
Answers
Answer:
now age of Appu is x years and age of Ammu is y years
before 2 years Appu was (x-2) years and Ammu was (y-2)years
so,
x-2=6(y-2)
=> x=6y-12+2
=> x=6y-10
after 4 years Appu will be (x+4)years and Ammu will be (y+4)years
x+4=3(y+4)
=> x=3y+12-4
=> x=3y+8
so,
6y-10=3y+8
=> 6y-3y=8+10
=> 3y=18
=> y=18/3
=> y=6
so, x=3.6+8=18+8=26
so ,now Appu is 26 years and Ammu is 6 years old
Answer:
Present ages
Let Ammu's present age be x
Past ages
Ammu's age 2 years ago = x-2
Then, Appu's age will be 6(x-2) = 6x-12
Future Ages
Ammu's age after 4 years = x+4
Then, Appu's age will be 3(x+4) = 3x+12
Assuming that Ammu's age is constant in past and future :
(6x-12) + (6 years) = 3x+12
6x -6 = 3x+12
3x = 18
x = 18/3 = 6
If Ammu's age is 6, Appu's age can be found out by substituting x with any of the formulas (6x-12 or 3x+12)
Appu's past age will be (6*6 - 12) = 24
So, Appu's present age will be 24+2 = 26 years
Final Answer :
Ammu's age = 6 years
Appu's age = 26 years
