Given that,

$\text{Cost of 4 table } = 120 \times 4\\\\\text{Cost of 4 table } = 480$

Also given that,

$\text{Cost of 6 chairs } = 3000 \times 3 \div 4\\\\\text{Cost of 6 chairs } = 2250$

Find the cost of 4 chairs

$\text{Cost of 1 chair } = \frac{2250}{6} = 375$

Therefore,

$\text{Cost of 4 chair } = 375 \times 4 = 1500$
