Answer 1

$\sf { {\: Let \: George's \: salary \: be \: x.}}$

$\sf {Anna's \: salary = \dfrac{7}{5} x}$

$\sf \: Together \: they \: earn = Rs. 360$

$\sf \: A/Q,$

$\sf \: \dfrac{7}{5} x + x = 360 \\ \\ \sf \: \frac{7x + 5x}{5} = 360 \\ \\ \sf \: \frac{12x}{5} = 360 \\ \\ \sf \: 12x = 360 \times 5 \\ \sf \: 12x = 1800 \\ \sf \: x = \frac{1800}{12} \\ \\ \sf \red{\: x = 150...(ans)}$
