Solution : Let her monthly salary be $x$.
Kriti's EMI was 22% of her monthly salary.
$\therefore$ Remaining salary = $0.78x$
Spending on groceries and clothes was in the ratio of $7:5$.
Money spent on clothes = $\frac{5}{12} \times 0.78x$
According to the question,
$\frac{5}{12} \times 0.78x

Correct Answer: 10 litres 

Solution : Let the initial milk be $5k$ and water be $2k$ litres
Amount of water added = 4 litres 
Now, 
$\frac{5k}{2k+4}=\frac{5}{4}$
⇒ $20k=10k+20$
⇒$10K=20$
⇒ $k=2$
⇒ Amount of milk =$5k=5\times 2$= 10 litres 
Hence, the correct answer is 10 litres.

Correct Answer: 40 miles/hr

Solution : $\text{Average speed}=\frac{\text{Total distance}}{{\text{Total time}}}=\frac{220+220}{6+5}=\frac{440}{11}=40$ miles/hr
Hence, the correct answer is 40 miles/hr.

Correct Answer: $\tan^{2}\alpha$

Solution : Given: $\cos^{2}\alpha–\sin^{2}\alpha=\tan^{2}\beta$
We know that: $1+\tan^{2}\alpha=\sec^{2}\alpha$
So, $\cos^{2}\alpha-\sin^{2}\alpha=\sec^{2}\beta-1$
⇒ $\cos^{2}\alpha-\sin^{2}\alpha+1=\sec^{2}\beta$
⇒ $\cos^{2}\beta=\frac{1}{\cos^{2}\alpha–\sin^{2}\alpha+(\sin^{2}\alpha+\cos^{2}\alpha)}$
⇒ $\cos^{2}\beta=\frac{1}{2\cos^{2}\alpha}$
Also, $\sin^{2}\beta=1-\cos^{2}\beta=1-\frac{1}{2\cos^{2}\alpha}$
So, $\cos^{2}\beta-\sin^{2}\beta$
$=\frac{1}{2\cos^{2}\alpha}-(1-\frac{1}{2\cos^{2}\alpha})$
$= \frac{1}{\cos^{2}\alpha}-1$
$= \sec^{2}\alpha-1$
$= \tan^{2}\alpha$
Hence, the correct answer is $\tan^{2}\alpha$.
