$1 \frac{1}{3} - 1 \frac{1}{9} + 1 \frac{1}{6} = ?$

$A$ number,when divided by $296$,gives $75$ as the remainder. If the same number is divided by $37$,then the remainder will be:

$74.01 \%$ of $1301 + 9.99 \%$ of $1901 = ?$

Thrice the square of a natural number decreased by $4$ times the number is equal to $50$ more than the number. The number is

In a division sum,the divisor is $4$ times the quotient and twice the remainder. If $a$ and $b$ are respectively the divisor and the dividend,then

The numerator of a fraction is the product of two numbers. One of the numbers is greater than the other by $2$. The greater number is smaller than the denominator $D = 7+c$ (where $c > -7$ is a constant). If the fraction is $f(x) = \frac{(x-2)x}{x+k}$ (where $x$ is the greater number),find the minimum value of the fraction.
