(D) Given,the third number $= 2400$.The second number $= \frac{1}{4} \times 2400 = 600$.Let the first number be $x$. According to the problem,$\frac{6}{11}x = 22 \%$ of $600$.$\frac{6}{11}x = \frac{22}{100} \times 600$.$\frac{6}{11}x = 22 \times 6 = 132$.$x = 132 \times \frac{11}{6} = 22 \times 11 = 242$.Now,we need to find $45 \%$ of the first number $(242)$:$45 \% \text{ of } 242 = \frac{45}{100} \times 242 = 0.45 \times 242 = 108.9$.
