Question : A shopkeeper increases the price of an object by 40% and then sells it at a 25% discount on the marked price. If the selling price of such an object is Rs. 2100, its cost price for the shopkeeper is:
Option 1: Rs. 3,000
Option 2: Rs. 1,500
Option 3: Rs. 1,750
Option 4: Rs. 2,000
Correct Answer: Rs. 2,000
Solution : Here, Selling price of an object = Rs. 2,100 Here, $a$ = 40%, $b$ = –25% Effective percentage change = $a+b+\frac{ab}{100}$% = $40 − 25 −\frac{40\times 25}{100}$% = $(15 - 10)$ = 5% According to the question, Let the cost price of the article
Question : If $M =\left ( \frac{3}{7} \right ) ÷ \left ( \frac{6}{5} \right ) ×\left ( \frac{2}{3} \right ) + \left ( \frac{1}{5} \right ) ×\left ( \frac{3}{2} \right )$ and $N = \left ( \frac{2}{5} \right ) × \left ( \frac{5}{6} \right ) ÷ \left ( \frac{1}{3} \right ) + \left ( \frac{3}{5} \right ) × \left ( \frac{2}{3} \right ) ÷ \left ( \frac{3}{5} \right )$, then what is the value of $\frac{M}{N}$?
Option 1: $\frac{207}{560}$
Option 2: $\frac{339}{1120}$
Option 3: $\frac{113}{350}$
Option 4: $\frac{69}{175}$
Correct Answer: $\frac{113}{350}$
Solution : $M =\left (\frac{3}{7}\right) ÷ \left (\frac{6}{5} \right) ×\left (\frac{2}{3} \right) + \left (\frac{1}{5} \right) ×\left (\frac{3}{2}\right)$ $M =\left (\frac{3}{7} \right) × \left (\frac{5}{6} \right) ×\left (\frac{2}{3} \right) + \left (\frac{1}{5} \right) ×\left (\frac{3}{2} \right)$ $M = \frac{5}{21}+\frac{3}{10}$ $M = \frac{113}{210}$ $N = \left (\frac{2}{5} \right)

Question : ABCD is a cyclic quadrilateral. Sides AB and DC, when produced, meet at E and sides AD and BC, meet at F. If $\angle $ADC = 76$^\circ$ and $\angle$AED = 55$^\circ$, then $\angle$AFB is equal to:
Option 1: $34^\circ$
Option 2: $26^\circ$
Option 3: $29^\circ$
Option 4: $27^\circ$
Correct Answer: $27^\circ$
Solution :
We know that the sum of all the sides of the triangle is $180^\circ $. In $\triangle DAE$, $⇒ \angle ADC + \angle AED + \angle DAE = 180^\circ$ $⇒ 76^\circ+ 55^\circ+ \angle DAE = 180^\circ$ $⇒ 131^\circ+ \angle DAE = 180^\circ$ $⇒ \angle DAE
Question : The value of the expression $\left (1+\sec22^{\circ} +\cot68^{\circ} \right )\left (1-cosec\;22 ^{\circ} +\tan68^{\circ} \right )$ is:
Option 1: 0
Option 2: 1
Option 3: –1
Option 4: 2
Correct Answer: 2
Solution : Given, $\left (1+\sec22^{\circ} +\cot68^{\circ} \right)\left (1-cosec\;22 ^{\circ} +\tan68^{\circ} \right )$ ⇒ $\left (1+\sec22^{\circ} +\tan22^{\circ} \right)\left (1-cosec\;22 ^{\circ} +\cot22^{\circ} \right)$ ⇒ $\frac{(\cos22^{\circ}+1 +\sin22^{\circ})}{\cos22^{\circ}}\times \frac{(\sin22^{\circ}-1 +\cos22^{\circ})}{\sin22^{\circ}}$ ⇒ $\frac{((\cos22^{\circ}+\sin22^{\circ})^{2}-1}{\cos22^{\circ}\sin22^{\circ}}$ ⇒ $\frac{(\cos22^{\circ})^{2}+(\sin22^{\circ})^{2}+2\cos22^{\circ}\sin22^{\circ}-1}{\cos22^{\circ}\sin22^{\circ}}$ Since, $(\cos22^{\circ})^{2}+(\sin22^{\circ})^{2}=1$, $\left (1+\sec22^{\circ} +\cot68^{\circ} \right )\left (1-cosec\;22 ^{\circ} +\tan68^{\circ} \right )=\frac{2\cos22^{\circ}\sin22^{\circ}}{\cos22^{\circ}\sin22^{\circ}} = 2$. Hence, the correct
