My brother is 4 times as old as I am. Six years from now, he will be twice as old as I will be. How old is my brother now?
2 answers:
Let, the present age of yours = x
present age of your brother = 4x
After 6 years, 2(x+6) = 4x+6
2x+12=4x+6
2x=6
x=3, 4x=12
So, your brother is 12 years of age now.
Let my present age be x.
My brother is 4 times as old = 4*x = 4x
Six years from now:
My age would be x + 6
Brother's age would be: 4x + 6
Brother would be twice my age.
4x + 6 = 2*(x +6)
4x + 6 = 2*x + 2*6
4x + 6 = 2x + 12
4x - 2x = 12 - 6
2x = 6
x = 6 / 2
x = 3
Age of brother = 4x = 4*3 = 12
Brother = 12 years old now.
Hope this explains it.
