Find n, if 2P(5,3) = P(n,4)

Find n if : 2^5P_3= "^nP_4 .

Find n if ""^(n-1)P_(3) : ""^(n)P_(4) = 1:16 .

Find n if : 30 ^nP_6= "^(n+2)P_7 .

Find n if "^(n-1)P_3 : "^nP_4 =1:9 .

Find n if : "^(2n)P_3=100 ^nP_2 .

Find n, if ""^(2n)C_(1),""^(2n)C_(2) and ""^(2n)C_(3) are in A.P.

Evaluate P(E U F), if P(E) = 3/4 , P(F) = 2/5 and P(E/F) = 5/4

If P (n) is the statement : "n (n + 1) (n + 2) is divisible by 12”, prove that P(3) and P(4) are true, but P(5) is not true.

In the figure, if P is (2, 4, 5), find the co-ordinates of N.
