Question : What is the value of $\frac{1+\tan A}{\operatorname{cosec} A}+\frac{1+\cot A}{\sec A}$?
Option 1: $2\sec^2A$
Option 2: $\sec \mathrm{A} - \mathrm{cosec A}$
Option 3: $\sec \mathrm{A} + \mathrm{cosec A}$
Option 4: $2 \;\mathrm{cosec^2 A}$
Correct Answer: $\sec \mathrm{A} + \mathrm{cosec A}$
Solution : $\frac{1+\tan A}{\operatorname{cosec} A}+\frac{1+\cot A}{\sec A}$ $=\frac{1+\frac{\sin A}{\cos A}}{\frac{1}{\sin A}}+\frac{1+\frac{\cos A}{\sin A}}{\frac{1}{\cos A}}$ $=\sin A(1+\frac{\sin A}{\cos A})+\cos A(1+\frac{\cos A}{\sin A})$ $=\sin A(\frac{\cos A+\sin A}{\cos A})+\cos A(\frac{\cos A+\sin A}{\sin A})$ $=(\sin A+\cos A)(\frac{\sin A}{\cos A}+\frac {\cos A}{\sin A}))$ $=(\sin A+\cos A)(\frac{\sin ^2A+\cos^2A}{\sin A

Question : If a man purchases kishmish at INR 320 per kg and sells it at INR 6 per 25 grams, then his profit/loss percentage is:
Option 1: 20% loss
Option 2: 25% loss
Option 3: 25% profit
Option 4: 20% profit
Correct Answer: 25% loss
Solution : The cost price of 1 kg kishmish = INR 320 The selling price of 25 grams of kishmish = INR 6 The selling price of 1 kg kishmish = $\frac{6}{25}×1000$ = INR 240 Loss percentage = $\frac{\text{Cost price – Selling price}}{\text{Cost price}}×100=\frac{320-240}{320}\times 100=\frac{80}{320}×100=25\%$ Hence,

Question : Directions: Select the option that is related to the fifth number in the same way as the first number is related to the second number and the third number is related to the fourth number. 434 : 567 :: 617 : 750 :: 839 : ?
Option 1: 972
Option 2: 1334
Option 3: 984
Option 4: 1012
Correct Answer: 972
Solution : Given: 434 : 567 :: 617 : 750 :: 839 : ?
Like, 434 : 567→434 + 133 = 567 617 : 750→617 + 133 = 750 Similarly, follow the same pattern for 839 : ?→839 + 133 = 972
So, 972 is the required
