A positive number is 5 times another number. If 21 added to both the numbers, then one of the new numbers becomes twice the other new number. What are the numbers?
MEDIUM
Answer
Let the numbers be x,y
⟹y=5x
21 is added
The numbers are
y+21,x+21
According to question
y+21=2(x+21)
5x+21=2x+42
5x=2x+21
3x=21
x=7->y=35
