Detailed Solution
Download Solution PDFGiven:
Age ratio = 5 ∶ 4
Age difference = 8 years
Find younger student's age
Concept:
Ratio of two quantities of the same kind and in the same units is a fraction that shows how many times the one quantity is of the other.
Solution:
Difference in ratio = 5 - 4 = 1
Age corresponding to 1 part in ratio = Age difference = 8 years
Younger student's age = 4 parts in ratio × Age corresponding to 1 part in ratio = 4 × 8 = 32 years
Hence, the age of the younger student is 32 years (Option 2).
