Best ResponseYou've already chosen the best response.3i should mention that this reasoning type question doesn't necessarily involves math

Best ResponseYou've already chosen the best response.0Yeah, I mean sure, you don't have to make an equation and solve it. This is as verbal as I can get about the question... 80:90 is the same as 8:9. Now 15*8 = 120 so the question mark should be replaced by 15*9.

Best ResponseYou've already chosen the best response.0Uh, I read it as "equivalent to" or "corresponds to" or "same as" or whatever.

Best ResponseYou've already chosen the best response.0Are you sure the options are correct, mathmath?

Best ResponseYou've already chosen the best response.3it is used in reasoning /IQ type questions , where u have to find the pattern it may be more complex

Best ResponseYou've already chosen the best response.3and \(80/90=120/x\), \(x= 135\) is not in options

Best ResponseYou've already chosen the best response.3by doing some operation on 80, it is converted to 90 by applying the same operation on 120 u have to find the resulting number

Best ResponseYou've already chosen the best response.58 * 10 9 * 11 12 * 10 13 * 11 = 143 143 = 11 * 13 156 = 12 * 13 169 = 13 * 13 181 = prime

mathmath333

Best ResponseYou've already chosen the best response.3181 is the answer, wow

mathstudent55

Best ResponseYou've already chosen the best response.5I thought the answer was 143.

mathmath333

Best ResponseYou've already chosen the best response.3because all the others are composite

Best ResponseYou've already chosen the best response.1we're not doing "odd man out" here ;p

mathmath333

Best ResponseYou've already chosen the best response.3i mean by pattern he got 143 = 11 * 13 156 = 12 * 13 169 = 13 * 13 except 181

mathstudent55

Best ResponseYou've already chosen the best response.5Since 80, 90, and 120 are not prime, why would we think the last number should be prime?

mathstudent55

Best ResponseYou've already chosen the best response.5Then I was able to fit 143 as a continuation of the pattern, but not 181.

Best ResponseYou've already chosen the best response.5\(\large 80:99 :: 120:143\) \(\large 8 \times 10:9 \times 11 :: 12 \times 10: 13 \times 11\) \(\large 80:99 :: 120: 143\)

Best ResponseYou've already chosen the best response.1I think we can propose legit reasons for each other options to be the answers although 143 is more apparent one...

Best ResponseYou've already chosen the best response.1For example finding a \(k\) and \(l \) such that \[80k+l=90\\120k+l=any \ option\ \]
