QUESTION: 15

Two finite sets have m and n elements, the total number of subsets of the first set is 56 more than the total number of subsets of the second. The value of m and n are respectively

Solution:

Let A denote the first set and B denote the second set

We have, n(A) = 2^{m} and n(B) = 2^{n}

As per the question, we have

n(A) = 56 + n(B)

⇒ n(A) - n(B) = 56

⇒ 2^{m} - 2^{n} = 56

⇒ 2^{n} (2^{m - n} - 1)

⇒ 2^{n} (2^{m - n} - 1) = 8 x 7

⇒ 2^{n} = 8 = 2^{3} or (2^{m - n} - 1) = 7

⇒ n = 3 or 2^{m - n} = 8 = 2^{3} = 2^{6 - 3}

⇒ n = 3 or m - n = 3

⇒ n = 3 or m = 6

Hence, the required values of m and n are 6 and 3 respectively
