Let E be the ellipse x29+y24=1 and C be the circle

x2+y2=9. Let P(1, 2) and Q(2,1) be two points, then 

a
Q lies inside C but outside E
b
Q lies outside both C and E
c
P lies inside both C and E
d
P lies inside C but out side E

detailed solution

Correct option is D

C:x2+y2−9=0E:x2/9+y2/4−1=0.   For P(1, 2), C:1+4−9<0, E:19+44−1>0So P lies outside E and inside C.For Q(2,1),C:4+1−9<0, E:49+14−1<0So Q lies inside both C and E.
