Question

Example 2: The difference in the age of two people is 20 years. If 5 years ago, the elder one of the two was 5 times as old as the younger one, then their present ages are equal to:​

Answer 1

Answer:

25 & 5

Step-by-step explanation:

let one person age x and other y

Let x elder than y

ATQ: X-Y=20............(1)

5 years ago,

X Age = X-5

Y Age = Y-5

ATQ: X=5Y

Putting value of x in equation (1)

therefore, 5Y-Y = 20

4Y = 20

Y = 20/4

Y = 5

Putting value of y in (2)

X=5(5)

X=25
