the figure shows a 'double slit experimental set-up' for observing interference fringes due to different component colours of white light. what would be the predominant colour of the fringes at a point P where S2P - S1P = wavelength of blue/2

you forgot to attach figure. figure is attached by me. you can see it below.
answer : (i) at Central point , O : White colour fringe is obtained at point O as all components colour wavelength undergo constructive interference fringe pattern.
(ii) at a point P : In this case, the light of blue colour interfere destructively and hence this colour would subtract from white light. Thus, yellow colour fringe would be obtained at P.
