Average Percentage

270/400X100 = 67.5%

Therefore,Answer Is : Option A.(67.5%).

04.The ratioof total marks obtained by Yogi in HVDC and Measurements and that scored by Nani in Power Systems and VLSI is ?

A. 134:148
B. 148:133
C. 139:149
D. None of these E. 149:134

Explanation

Answer: Option E : 149:134
