In an exam, total marks of $x$ students in mathematics is $1950$ . With one new student scoring $34$ added, the average drops by $1$ . The equation derived is—

a $x^2 + 35x - 1950 = 0$
b $x^{2} - 35 x +$

ব্যাখ্যা

The original average is $\frac{1950}{x}$ , and after adding a student scoring $34$ the new average $\frac{1984}{x+1}$ is less. Setting and clearing denominators gives .
