Data related to number of candidates appeared and qualified in a competitive exam from 2 states during 5 years :
NOTE :Few values are missing in the table (indicated by —). A candidate is expected to calculate the missing value, if it is required to answer the given question on the basis of given data and information.
The number of appeared candidates from State Q increased by 100% from 2006 to 2007. If the total number of qualified candidates from State Q in 2006 and 2007 together is 408, what is the number of appeared candidates from State Q in 2006 ?
Note :- Increase by 100% means twice the previous value
Let appeared candidates from state Q in 2006 = 100x
=> appeared candidates from state Q in 2007 = 200x
Qualified candidates in 2006 = (30/100)*100x = 30x
Qualified candidates in 2007 = (45/100)*200x = 90x
Now, sum of qualified candidates in both years = 30x + 90x = 120x = 408
=> x =408/120 = 3.4
Ans = candidates appeared from state Q in 2006 = 100*3.4 = 340
