Question 32

# 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 ?

Solution

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
