200 can be expressed as product of two numbers


200= 1^6 * 200^1 ---------(1)
200= 2^2 * 50 ------ (2)
200= 10^2 * 2^1 ------ (3)
200= 2^3 * 5^2 ---------(4)

x > y satisfies (2), (3) an (4)

however xy=6 is satisfied by only (1) and (4)

for (1) x+y =7
for (4) x+y=5

together no additional help.

(E)
