Question

If the number of students in institutes P, Q and R with IT specialisation increased by 15%, 22% and 10% respectively from 2012 to 2013, what was the total number of students with IT specialisation in the three institutes together in 2013?

• A. 1028
• B. 1056
• C. 1043
• D. 1142
• E. 1145

Answer 1

The correct option is C 1043

Total number of students in institutes P, Q and R with IT specialisation in 2013,
$=340\times \frac{115}{100}+\frac{300\times 122}{100}+\frac{260\times 110}{100}$
$=340\times 115+3\times 122+2.6\times 110$
$=391+366+286=1043$.
