Solution

According to ques,

=> $$(\frac{1}{4} \times x) - (\frac{4}{5} \times \frac{6}{7}) = \frac{-9}{7}$$

=> $$\frac{x}{4} - \frac{24}{35} = \frac{-9}{7}$$

=> $$\frac{x}{4} = \frac{24}{35} - \frac{9}{7}$$

=> $$\frac{x}{4} = \frac{24-45}{35} = \frac{-3}{5}$$

=> $$x = \frac{-3}{5} \times 4 = -2.4$$

=> Ans - (B)
