Here G is not only commutative but also a cyclic group as G contains an element of order lcm(2,101) i.e. 202.So G has exactly phi(2) i.e 1 element of order 2.

@@pde9322 what abt D101
@@nadeemnazir295 The dihedral groups Dn are non-abelian for n≥3.Here n=101(odd) , so the number of elements of order 2 will be 101.

@@nadeemnazir295 ok👍
Are bhai ye galat padhata hai ispe bharosa mat kro sala gcd 1 to cyclic aata hai nhi kuch
Thanks ur feedback ....but jo bi pdhaya h n isme fr se pdho ki btaya kya h usme uske baad bolo
Tumne gcd 1 per cyclic bola hai ab ye order 111 pe lagana
