Question

1) What is John's present age , if after 10 years of his age will be 5 times his age 5 years back.​

Answer 1

Answer :-

☆ Present age = 8.75 years

Step - by - Step explanation :-

♡ Let John’s present age be x

♡ John’s age before 5 years = (x - 5)

♢ John’s age after 10 years = (x + 10)

We are given that, John’s age after 10 years (x + 10) is 5 times his age 5 years back (x – 5)

Therefore,

(x + 10) = 5 (x – 5)

Solving the equation, we get

➵ x + 10 = 5x – 25

➵ 4x = 35

➵ x = 8.75 years

Therefore, Present age of John is 8.75 years
