hello friend
Let the worth of total estate as x
$\frac{4}{5} \times x = 42000 \\ \: \: \: \: \: \: \: \: \: x = \frac{5}{4} \times 42000 \\ \: \: \: \: \: \: \: \: \: x = 52500 \\ \frac{3}{7} \times x = \frac{3}{7} \times 52500 \\ \frac{3}{7} \times x = 22500$
the worth is 52500 and 3 by 7 of it is 22500.
