Y represent the number of students in a class who cleared the verbal section.

Z represents the number students in a class who cleared the reasoning section.

 

Answer:

Option D

Explanation:

From the venn Diagram we get,

exactly one+2(exactly two)+3(exactly three)=124+119+142=385--------(1)

exactly one+3(exactly three )$ = (75+64+91)+3\times 10=261$--------(2)

Subtracting(2) from (1) we get,

$\therefore$ 2(exactly two)$=124$

$\therefore$ exactly two$=62$

$\therefore$ number of students =exactly one+exactly two+exactly three+none

=(75+64+92) +62+10+2=305
