The unit digit in the sum $(124)^{372} + (124)^{373}$ is

What least number must be subtracted from $1294$ so that the remainder when divided by $9, 11, 13$ will leave in each case the same remainder $6$?

$2439.97 - 1234.01 + 401.99 = ? + 989.99$

$1 \frac{5}{6} + 2 \frac{3}{5} + 4 \frac{2}{3} = ?$

$18 \%$ of $125 \times 9 \%$ of $25 = ? - 100$
