What will come in place of the question mark (?) in the following questions ? $$\frac{4}{9}of\frac{3}{16}of\frac{6}{13}of ?=155$$

Explanation

Expression : $$\frac{4}{9}of\frac{3}{16}of\frac{6}{13}of ?=155$$ => $$\frac{4}{9} \times \frac{3}{16} \times \frac{6}{13} \times x = 155$$ => $$1 \times \frac{1}{2} \times \frac{1}{13} \times x = 155$$ => $$x = 155 \times 26 = 4030$$
