Solution
Verified by Toppr

Equivalent weight=Molecular weightNumber of Equivalents
In case of:
H3PO4+OHH2PO4+H2O
H+ ions given = 1
Thus the number of equiv=1
Equivalent weight=981=98
In case of:
H3PO4+2OHHPO24+2H2O
H+ ions given = 2
Thus the number of equiv=2
Equivalent weight=982=49
In case of:
H3PO4+3OHPO34+3H2O
H+ ions given = 3
Thus the number of equiv=3
Equivalent weight=983=32.67
