Directions (Next Six Questions) : study the following graph carefully to answer the given questions .
Strength of even technology institutes with
Speciallisations in IT. Electronics
and mechanical in 2012
Institute
If the number of students with Mechanical Specialisation in each institute increased by 20% and the number of students with Electronic specialisation in each institutes decreased by 15% from 2012 to 2013, total number of students with Mechanical from all the institutes in 2013 is approximately, what percent of the total number of students with Electronics specialisation from all the institutes in 2013 ?
Total number of students in Mechanical after increased by 20% = 2120 ×120/100 = 2544
Total number students in electronics after decreased by 15% = 1680 × 85/100 = 1428
∴ Required Percentage = 2544/1428 ×100
=178%
