16xplanation :   Let the number of ducks be d   and number of goats be c   Then, total number of legs = 2d + 4c = 2(d + 2c)   total number of heads = c + d   Given that total number of legs are 32 more than twice the number of heads   =&gt; 2(d + 2c) = 32 + 2(c + d)   =&gt; d + 2c = 16 + c + d   =&gt; 2c = 16 + c   =&gt; c = 16   i.e., total number of goats = 16   Answer : 16
