The process of heating sugars or carbohydrates is called caramelisation. Food should change for the better as it gets hot enough because it forms new compounds and browns. Two non-enzymatic browning processes that take place in food include caramelisation and

Correct Answer: $\sqrt{3}$

Solution : $7 \sin ^2 A+3 \cos ^2 A=4$
$7 \sin ^2 A+3(1-\sin ^2 A)=4$
$7 \sin ^2 A+3-3 \sin ^2 A=4$
$4 \sin ^2 A=1$
$ \sin ^2 A=\frac{1}{4}$
$ \sin A=\frac{1}{2}$
$\therefore A = 30^{\circ}$
$\cot A = \cot 30^{\circ} = \sqrt3 $
Hence, the

Correct Answer: 45

Solution : Let the speed of the train and the car be $a$ km/h and $b$ km/h, respectively.
According to the question,
$\frac{240}{a}+\frac{450–240}{b}=8\frac{40}{60}$
⇒ $\frac{240}{a}+\frac{210}{b}=\frac{26}{3}$ ---------------------------(equation 1)
Also, $\frac{180}{a}+\frac{450–180}{b}=9$
⇒ $\frac{180}{a}+\frac{270}{b}=9$ --------------------------------------(equation 2)
Multiply equation 1 by 3 and equation 2 by 4 we get,
$\frac{720}{a}+\frac{630}{b}=26$ --------------------------------------(equation

Correct Answer: Cast iron

Solution : The correct option is Cast iron.

Cast iron is an alloy with a carbon content of 2–5%. Hard steel is an iron alloy with a relatively low carbon content. Hence, a minor amount of carbon is added to boost its strength. Steel is also

Correct Answer: 18

Solution : We know the algebraic identity, $(a-b)^{2} = a^{2}+b^{2}-2ab$.
By substituting the values of $a-b = -7$ and $a^{2}+b^{2} = 85$ in the above equation, we get,
$⇒(–7)^{2} = 85-2ab$
$⇒49 = 85-2ab$
$⇒-36 = -2ab$
$\therefore ab=18$
Hence, the correct answer is 18
