Let S be the set of points, whose abscissae and ordinates are natural numbers. Let p e S, such that the sum of the distance of P from (8, 0) and (0, 12) is minimum among all elemants in S. Then, the number of such points P in S is
1

If , then x lies in the interval
(1, 2)
(- 2, - 1)
None of these
A.
Hence, x lies in the interval (2, ).
If p.q are the · roots of the equation x2 + px + q =0, then
p = 1, q = - 2
p = 0, q = 1
p = - 2, q = 0
p = - 2, q = 1
The number of ways in which the letters of the word ARRANGE can be permuted such that the R's occur together, is
