Question 145

The given bar chart presents the average marks obtained in English (E) and vernacular (V) by the students of five districts (D1, D2, D3, D4, D5)in a state at the secondary level examination of a particular year (marks secured out of a total of 100).

What is the difference between the average percentage of marks in vernacular of the districts (D1, D2, D4) and (D3, D5)?

Solution

Average percentage of marks in vernacular of the districts (D1, D2, D4) = $$\frac{(80+70+75)}{3}=\frac{225}{3}=75$$

Average percentage of marks in vernacular of the districts (D3, D5) = $$\frac{(50+55)}{2}=\frac{105}{2}=52.5$$

=> Required difference = $$75-52.5=22.5\%$$

=> Ans - (D)
