Given : A fraction

If numerator is multiplied by 3 and denominator is decreased by 3 then fraction becomes 8/11

If numerator is increased by 8  and denominator is  doubled then fraction becomes 2/5

To Find: Fraction

Solution:

Fraction = N/D

N = numerator

D = Denominator

3N/(D - 3) = 8/11

=> 33N = 8D - 24

=> 33N + 24 = 8D

(N + 8)/2D = 2/5

=> 5N + 40  = 4D

=> 10N + 80 = 8D

Equate 8D

33N + 24 = 10N + 80

=> 23N  = 56

N should have been integer

Correct Question can be : 18/11 instead of 8/11

Fraction = N/D

N = numerator

D = Denominator

3N/(D - 3) = 18/11

=> 33N = 18D - 54

=> 33N + 54 = 18D

=> 11N + 18 = 6D

=> 22N + 36 = 12D

(N + 8)/2D = 2/5

=> 5N + 40  = 4D

=> 15N + 120 = 12D

Equate 12D

22N + 36 = 15N + 120

=> 7N  = 84

=> N = 12

15(12) + 120 = 12D

=> 15 + 10 = D

=> D = 25

Fraction = 12/25
