Study the following graph carefully to answer the given questions.
Number of candidates who qualified in a given competitive examination from 6 states during two given years :
What is the respective ratio between total number of qualified candidates from state T in 2004 and 2005 together and total number of qualified students from state U in 2004 and 2005 together?
Total number of qualified candidates from state T in 2004 and 2005 = 840 + 540 = 1380
Total number of qualified students from state U in 2004 and 2005 together = 420 + 300 = 720
=> Required ratio = 1380 : 720
= 23 : 12
