Question

In Young’s double slit experiment the two slits act as coherent sources of equal amplitude A and wavelength $λ$ . In another experiment with the same set-up the two slits are source of equal amplitude A and wavelength $λ$ , but are incoherent. The ratio of the intensity of light at the midpoint of the screen in the first case to that is second case is
