Correct Answer: 107

Solution : Given: 
+ and – and × and ÷ are interchanged.
13 ÷ 145 × 29 – 69 + 27 = ?

After interchanging the symbols according to the question, the equation is as follows –
⇒ 13 × 145 ÷ 29 + 69 – 27

Correct Answer: 2077 : 2205

Solution : According to the given bar graph, we have
Total production of steel in the years 1924 and 1925 = 77.23 + 88.93 = 166.16
Total production of steel in the years 1923 and 1927 = 76.23 + 100.17 = 176.40
Required ratio =

Correct Answer: $\left(a^2-b^2\right)$

Solution : Given, $A=a \operatorname{cosec} \theta+b \cot \theta$ and $B=a \cot \theta+b \operatorname{cosec} \theta$
To find, $A^2-B^2$
Let us find the value of $A^2$ and $B^2$ first,
$A^2 = (a \operatorname{cosec} \theta+b \cot \theta)^2$
$A^2 = a^2 \operatorname{cosec}^2\theta + b^2\cot^2\theta + 2ab\operatorname{cosec}\theta\cot\theta$
Now, $B^2 = (a \cot
