Solution

$y$ % of $250 = 21$

$⟹ \frac{y}{100} \times 250 = 21$

$⟹ y = 21 \times \frac{100}{250}$

$∴ y = \frac{42}{5}$

12 x + 13 y = 29

13 x + 12 y = 21

y = 2^{\frac{1}{{log}_{x} 4}}

x = 9

x = y^{3} + 4 y

y = \frac{7}{k}

k = 21

\frac{2}{x} + \frac{3}{y} = \frac{9}{x y} and \frac{4}{x} + \frac{9}{y} = \frac{21}{x y}
