Internity is directly proportional to the width of the slit .
Also intensity is directly proportional to the square of the amplitude
Then
w1/w2 = I1/I2 = a2/b2
4/9 = a2/b2
So b = 3a/2
ratio of intensity of maxima to minima = (a+b)2/(a-b)2 = 25:1.
Hope it clears. If you like answer then please approve it.
