Question

Read the information given below to answer the question.

Diana is three times older than Jackson. Edward is half the age of Stephen. Jackson is older than Edward.

Which one of the following information will be sufficient to estimate Diana's age?

विकल्प

• Edward is 10 year old

• Both Jackson and Stephen are older than Edward by the same number of years.

• Both A and B

• None of the above

Answer 1

Both A and B

Explanation:

Let the age of Jackson and Stephen both be  (10 + x) yr. Now, 2E = S => 2 × 10 = 10 + x => x = 10 yr.  
`therefore` Jackson’s age = 10 + x = 20 yr  
Hence, Diana’s age = 3 × 20 = 60 yr
