Question

33. Decide, among the following sets, which sets
are subsets of one and another:
A={r:reR and satisfy r? - 8x +12=0}
B = {2,4,6}, C = {2,4,6,8,...), D = {6}.​

Answer 1

Answer:

A={x:x∈Rand x satisfiesx

2

−8x+12=0}

2 and 6 are the only solutions of x

2

−8x+12=0.

∴A={2,6}

B={2,4,6}

C={2,4,6,8,....}

D={6}

Clearly, D⊂A⊂B⊂C

Hence, A⊂B,A⊂C,B⊂C,D⊂A,D⊂B,D⊂C
