Kudos for the right answer and explanation
Question part of the project GRE Quantitative Reasoning Daily Challenge - (2021) EDITIONGRE - Math BookLet x = Chetan's age IN 2002
This means
2002 - x = Chetan's BIRTH YEAR
The age of Mr. Chetan in 2002 was 1/90 of his birth year. We can write: x = (1/90)(
2002 - x)
To eliminate the fraction, multiply both sides of the equation by 90 to get: 90x = (
2002 - x)
Add x to both sides: 91x = 2002
Solve: x = 2002/91 =

22 years old in 2002
