दिलेल्याप्रमाणे

वडिलांचे वय त्यांच्या मुलाच्या 4 पट आहे.

5 वर्षांपूर्वी वडिलांचे वय त्यांच्या मुलाच्या 5 पट होते.

गणना:

समजा, 4x = वडिलांचे सध्याचे वय, x = मुलाचे सध्याचे वय

5 वर्षांपूर्वी वडिलांचे वय त्यांच्या मुलाच्या 5 पट होते.

 4x -5 = 5(x - 5) 

⇒ 4x - 5 = 5x - 25

⇒ x = 20

∴ वडिलांचे सध्याचे वय = 4 (20) = 80 वर्षे.
