At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?

In Young’s double slit experiment, the slits are 2 mm apart and are illuminated by photons of two wavelengths λ1 ​= 12000 A and λ2​ = 10000 A. At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?

a point on the screen corresponding to the fifth minimum has path difference​ if there is no initial phase difference between the light from the two slits In a Young's double slit experiment In Young's double slit experiment
