Verified Answer
In a YDSE bi-chromatic light of wavelength 400 nm and 560 nm are used....
Let nth minima of 400 nm coincides with mth minima of 560 nm, then

4th minima of 400 nm coincides with 3rd minima of 560 nm. 
Location of this minima is

Next 11th minima of 400nm will coincide with 8 minima of 560 nm 
Location of this minima is

∴      Required distance = y2 - y1 =28
