1.Let A={1,2,3,…,10}A = \{1, 2, 3, \ldots, 10\}A={1,2,3,…,10} and B={mn∣m,n∈A,m<n and gcd(m,n)=1}B = \{\frac{m}{n} \mid m, n \in A, m < n \text{ and } \gcd(m, n) = 1\}B={nm∣m,n∈A,m<n and gcd(m,n)=1}. Then n(B)n(B)n(B) is equal toa.363636b.313131c.373737d.292929Login to continueOnly logged in users canattempt or see the solution.
