Here we need to calculate alternate depth (not conjugate depth).
So we can not use hydraulic jump formula y2/y1 = 1/2[-1+sqrt(1+8Fr2)] because this formula has driven from a specific force equation and it is used for finding conjugate depth only. But in question ask alternate depth which can be found by equating specific energy.
