$(1567+14\mathrm{.}50)+(109+17\mathrm{.}60)=$

$1679+02\mathrm{.}10$

$1678+02+11$

Nothing of all mentioned above

$1678+02\mathrm{.}10$

$1676+28\mathrm{.}10$

A crest vertical curve joined $(+4\%)$ grade and $(-6\%)$ grade $.$ if the elevation of point EVC $(88\mathrm{.}8$ m $).$

Determine the elevation of BVC and PVI for this curve using K value Method for speed $85k\frac{m}{h}.$

$BVC=96\mathrm{.}885,$PVI$=105\mathrm{.}885$

$BVC=98\mathrm{.}05,$PVI$=91\mathrm{.}885$

$BVC=102\mathrm{.}1,$PVI$=107\mathrm{.}85$

No Answer is correct

$BVC=91\mathrm{.}885,$PVI$=98\mathrm{.}05$
