In a beauty contest, half the number of experts voted Mr. A and two thirds voted for Mr. B 10 voted for both and 6 did not for either. How may experts were there in all.

NIMCET Previous Year PYQNIMCET NIMCET 2019 PYQ

#### Solution

Let the total number of experts be $N$.
$E$ is the set of experts who voted for miss $A$.
$F$ is the set of experts who voted for miss $B$.
Since $6$ did not vote for either, n$\left(E\cup F\right)=N-6$.
$n\left(E\right)=\frac{N}{2},\phantom{\rule{thickmathspace}{0ex}}n\left(F\right)=\frac{2}{3}N$ and $n\left(E\cap F\right)=10$
.
So, $N-6=\frac{N}{2}+\frac{2}{3}N-10$
Solving the above equation gives

If A > 0, B > 0 and A + B = $\frac{\pi}{6}$ , then the minimum value of $tanA + tanB$

NIMCET Previous Year PYQNIMCET NIMCET 2019 PYQ

#### Solution

On differentiating
x= tanA + tan(π/6-A)
we get :
dx/dA = sec²A-sec²(π/6-A)
now putting
dx/dA=0
we get
cos²(A) = cos²(π/6-A) so 0≤A≤π/6
therefore
A=π/6-A from here we get A = π/12 = B
so minimum value of that function is
2tanπ/12 which is equal to 2(2-√3)

⇒ $x=\frac{1}{2}\log _{10}\Bigg{(}\frac{1+y}{1-y}\Bigg{)}$

⇒ ${f}^{-1}(y)=\frac{1}{2}\log _{10}\Bigg{(}\frac{1+y}{1-y}\Bigg{)}$
