Whats the problem in the solution given by kp1811
@Bunuel for your question for st2 the total comes as 246,000 apprx so again st2 is suff...
If statement (2) were: "If the population were three times as large, the community board would have had 58 members."
Then according the solution given in previous posts the answer would be:
25 members represent first 500,00;
Remaining 33 will represent 33*30,000=990,000.
Total 500,00+990,000=1,490,000. As this is 3 times the current population, so we have 1,490,000/3=~497,000<500,000, hence sufficient.
But this would be wrong. As 1,490,000 will be the lowest possible population for 58 members, the highest would be 1,490,000+29,999=1,519,999. Meaning that 25 members for 500,000 plus 990,000 for 33 remaining members plus 29,999 of population with no member at all. In the case of highest possible population for 58 members, current population would be 1,519,999/3=~506,666>500,000. We have two answers one less than 500,000 another more. Not sufficient.
In our original question range for 51 members would be from 1,280,000(500,00+26*30,000) to 1,309,999(500,00+26*30,000+29,999). But as 1,309,999 (highest possible population for 51 members) divided by 3 is also less than 500,000 this didn't affect the final answer.
Hope it's clear.
