Question

the sum of shika's age and ravi's age is 73 . four years from now, shika's age will be twice ravi's age . Find their present ages

Answer 1

x+y=73
x+4=2(y+4)
x=2y+4
2y+4+y=73
3y=69
y=23
so present ages are 19 and 54
thank you

Answer 2

Let the age of ravi be x
Age of shika =y
According to the question,,
x + y = 73,, y=73-x
After 4 years,,
Age of ravi = x+4
Age of shika=y+4
According to the question after 4 years
Age of shika =2 times age of ravi
Y+4 =2(x+4)
Substitute y in terms of x and solve
73-x=2x+8
