The class with the highest frequency is 40–50, frequency = 35

\text { Mode }=L+\left(\frac{f_1-f_0}{2 f_1-f_0-f_2}\right) \times h

\text { Mode }=40+\left(\frac{35-20}{2(35)-20-21}\right) \times 10

=40+\left(\frac{15}{70-41}\right) \times 10=40+\left(\frac{15}{29}\right) \times 10 \approx 40+5.17

\text { Mode } \approx 45.17
