Question

आज से रहमान की 5 वर्ष बाद और 3 वर्ष पहले की उम्र का व्युत्क्रम का योग 1/3 हो , रहमान के वर्तमान उम्र होगी
​

Answer 1

Answer:

let Rehman's age X

after 5 years his age would be X+5

and 3 years ago his age was x-3

according to the question

1/X+5 + 1/ x-3 = 1/3

or it could be 2x+2/x^ +2x-15 =1/3

or 6x+6=x^ +2x-15

or x^ -4x-21

(X=7) (X=-3)

leave negative result

thus Rehman's present age = 7
