(1)It is observed that one-third of the marks obtained by Romit in Logical Analysis is greater than half of his marks obtained in Verbal English By 5.$\frac{b}{3}-\frac{a}{2}=5$$2b-3a=30$.....(2)On solving equation (1) and (2) we get $b=90$ and $a=50$Hence, the difference between the marks obtained by him in Mathematics and Verbal English $=70-50=20.$Therefore, option C is the correct answer.
