Answer 2

Answer:

Giat's mark is 34

Siat's mark is 80

Step-by-step explanation:

$let \: siat's \: marks \: be \: x \: \\ </p><p>as \: per \: questions</p><p>.$

$gitas \: marks = 2 + \frac{2}{5} x \\ again \\ 2 + \frac{2}{5} x - 4 = \frac{3}{8} x \\ \frac{2}{5} x - \frac{3}{8} x = 2 \\ \frac{16 - 15}{40} x = 2 \\ x = 80$

$giats \: mark = 2 + \frac{2}{5} \times 80 \\ 2 + 32 \\ 34$
