Why is the answer in the question different from that of the solution?

lQ 9: A U-tube differential manometer is
connected to two pipes at A and B. Pipe A
Contains oil of Specific Gravity 0.92 and
pipe B is carrying water. If the pressure at
point A is 125 kN/m² find the pressure at
point B. [Ans: h= -3.098 m, p = 30.39 kN/m²]
