Here is your answer.
Let the number be x
ATQ
$\frac{25}{100} \times \frac{3}{7} \times \frac{26}{100} \times x = 145.5 \\ x = \frac{145.5 \times 100 \times 7 \times 4}{3 \times 26} \\ x = 5223.07 \\ x = 5223$
So The number is 5223

Answer 2

Here is your answer

Let the number is x
$\frac{25}{100} \times \frac{3}{7} \times \frac{26}{100} \times x = 145.5 \\ \frac{1}{4} \times \frac{3}{7} \times \frac{13}{50} \times x = 145.5 \\ x = \frac{145.5 \times 4 \times 7 \times 50}{3 \times 13} \\ x = 5223.07 \\ x = 5223$
The number is 5223
