प्रश्न
A and B are together 90 years old. Five years ago A was thrice as old as B was. Hence, the ages of A and B five years back would be (x – 5) years and (85 – x) years respectively.
विकल्प
True
False
उत्तर
This statement is True.
Explanation:
Let the age of A be x years.
Then, age of B = (90 – x) years
Five years ago, the age of A = (x – 5) years
The age of B = 90 – x – 5 = (85 – x) years
Hence, the ages of A and B five years back would be (x – 5) years and (85 – x) years, respectively.
