Answer 1

Answer:

$let \: the \:missing \: no. \: be \: x \\ \frac{48}{1000} \times 6000 + \frac{33}{1000} \times 5000 - \frac{21}{1000} \times x = 432 \\ 288 + 165 - \frac{21x}{1000} = 432 \\ \frac{ - 21x}{1000} = 432 - 453 \\ \frac{ - 21x}{1000} = - 21 \\ x = - 21 \div \frac{ - 21}{1000} \\ x = - 21 \times \frac{1000}{ - 21} \\ x = 1000$
