Two load tests were performed at a site-one with a 50 cm square plate and the other with a 75 cm square plate. For a settlement of 15 mm, the loads were recorded as 50 kN and 90 kN, respectively in the two tests. Verify the allowable bearing pressure of the sand and the load which a square footing, 1.5 m size, can carry with the settlement not exceeding 25 mm.
