from the question, x = 2 , y = 1 OR x = -2 , y = 4

max value of (x^2)*(y^3) is 4 * 64 = 216

numbers are given to be positive

i think an approximation of .06 is possible i suppose and i would mark the answer as 6
anyways i have rechecked my solution and did not find any mistakes....

that means fractions are possible too...

ur answer is not present in the options

thus 3x + 4y = 27


i think this one also can be approached that way .... not sure though
y = 1 x = 2
thus 1 * 4 = 4

thanks for the solution

thanx buddy... by putting x= y we can get max value...


so answer is 6

In a classroom there are 14 students seated in 3 rows of 5 chairs. The place at the center of the room is unoccupied. A teacher decides to reassign the seats such that each student will occupy a chair adjacent to his/her present one (i.e. move one desk forward, backward, right or left). In how many ways can this reassignment be done?
(1) 1 (2) 13 (3) 0 (4) 27 (5) none of these
