Question

एक पिता की आयु पुत्र की आयु की 4 गुनी है 7 वर्ष बाद पिता की आयु पुत्र की आयु की 2.5 गुनी हो जाएगी​

Answer 1

Answer:

age of son= 91 years

age of father= 364 years

Step-by-step explanation:

age of son= x

age of father= 4x

After 7 years,

age of son= x+7

age of father= 4x+7

According to question,

2.5 (x + 4x) = 4x + 7 + x + 7

2.5x + 10.0x = 5x + 14

12.5x = 5x + 14

12.5x - 5x = 14

7.5x = 14

x = 14×7.5

x = 91.0
