$6\mathrm{.}35$ A well$-$graded silty sand with a maximum dry unit weight of $19\mathrm{.}7k\frac{N}{m^3}$ and an optimum

moisture content of $11\mathrm{.}0\%,$ obtained from the modified Proctor test, is being used to build a

compacted fill. Two field density tests have been taken in the recently completed fill, but one

of these tests has produced results that are definitely incorrect. Test A indicated a relative

compaction of $85\%$ and a moisture content of $8\mathrm{.}9\%,$ while Test B indicated a relative com$-$

paction of $98\%$ and a moisture content of $14\mathrm{.}9\%.$ Which test is definitely incorrect? Why?
