A.

5860

B.

6400

C.

4650

D.

3535

Correct option is D

Given:
30% of 50% of 47 \frac{4}{7}​ of a number = 303
Solution:
Let the number be x.
Formulate the equation:
30100×50100×47×x=303\frac{30}{100} × \frac{50}{100} × \frac{4}{7} × x = 303​​

310×12×47×x=303\frac{3}{10} × \frac{1}{2} × \frac{4}{7} × x = 303​​

12140×x=303\frac{12}{140} × x = 303​​

x=303×14012x = \frac{303 × 140}{12}​​

x = 3535
Final Answer
So the correct answer is (d)
