“7 men have 7 wives. I count that as 14 people because if they had specified “…7 wives each” then I would’ve said each man has 7 wives. Anyways. 14. Then ‘each man & each woman have 7 children’, so 1 family has 7 children. As there are 7 families here consisting of a mother and a father, 7×7 = 49. 14 + 49 = 63 people,” expressed a third.
