Question

if nCr=56 and nPx+336 then n =

Answer 1

we know that nCr equal to both 56 and nPx+336
so,nCr equal to nPx+336
nCr equal to 56
56equal to nPx+336
-nPx equal to 336-56
nPx equal to -280
n equal to -280/px
hence nCr equal to Px
n equal to -280/Px (Px equal to 56)
n equal to -280/56
hence n equals to -5
