7500
4500
4800
3400

Explanation

Let total income be = $x$
after spending $20 %$ of x he has = $\frac{8 0}{1 0 0} x$

after spending $70 %$ of remaining he has
= $\frac{3 0}{1 0 0} \times \frac{8 0}{1 0 0} x$
$\frac{3 0}{1 0 0} \times \frac{8 0}{1 0 0} x = 1800$
$x = \frac{1 8 0 0 \times 1 0 0}{2 4} = 300 \times 25 = 7500$
