Previous Year Question (PYQs)
Let the line $x = -1$ divide the area of the region
${(x,y) : 1 + x^2 \le y \le 3 - x}$
in the ratio $m : n$, $\gcd(m,n) = 1$. Then $m+n$ is equal to:
Solution
$\frac{m}{n} = \frac{\int_{-2}^{-1} \left[(3-x) - (1+x^2)\right] dx}{\int_{-1}^{1} \left[(3-x) - (1+x^2)\right] dx} = \frac{20}{7}$
$\Rightarrow m + n = 20 + 7 = 27$
