प्रगति की 2 वर्ष पहले की आयु और 3 वर्ष बाद का गुणनफल 84 है। लेकिन आयु ऋणात्मक नहीं हो सकती है, इसलिए x = 9। इस प्रकार, प्रगति की वर्तमान आयु 9 वर्ष

Answer:

9 years

Explanation:

hello Satish I'm also  from MH but don't know typing so me tumhala asa answer deil k.

Pragaticha aajacha vay = x

2 varshanpurvicha vay = x - 2

3 varshanantarcha vay = x + 3

(x-2) * (x+3) = 84

on multiplying

x^{2} + x -6 = 84

x^{2} + x -6 -84 = 0

x^{2} + x -90 = 0

x^{2} +10x - 9x -90 = 0

(x + 10) * (x-9) = 0

x = -10 and x = 9

so age is not considered as negative hence x = 9 years
