Question

There are 4 siblings, 1 sister who is eldest and 3 younger brothers whose ages are equally spaced. Sum of brothers ages is equal to age of of the sister, however, 5 years ago, sum of age of brothers was half that of sister now. What is her present age (in years)?
​

Answer 1

Answer:

According to question,

When you was 10 your brother was half your age(i.e. 10× 1/2 = 5 years)

It means you are 5 years older than your brother (i.e. age difference = 5 years)

Note: This age different is permanent i.e. it is not changed with time.

Now your brother is 50, then your age would be:

= Your Brother's present age + Age Difference

= 50 years + 5 years

= 55 years.

Hence, your age is 55 years.
