JEE Main 2025 Physics question

The width of one of the two slits in Young's double slit experiment is d while that of the other slit is xd. If the ratio of the maximum to the minimum intensity in the interference pattern on the screen is 9 : 4 then what is the value of x? (Assume that the field strength varies according to the slit width.)
