Given, Number of adults > Number of boys > Number of girls> Number of families Going back from the choices, let us start with the least value given in the choices. Since the minimum possible number of families has been asked.In choice (c) Number of families = 2 ⇒ Number of girls ≥ 3, Number of boys ≥ 4 and Number of adults ≥ 5. But two families together can have a maximum of 4 adults ≥ 5. But two families together can have a maximum of 4 adults. Therefore, the number of families is not equal to 2. In choice (d). Number of families = 3. Therefore, the Number of (girls) ≥ 4. Number of (boys) ≥ 5 and Number of (adults) ≥ 6.
