Question : A dishonest shopkeeper sells mangoes at INR 30 per kg, bought at INR 20 per kg, and he is giving 800 g instead of 1 kg. The shopkeeper's actual profit percentage is:
Option 1: 75%
Option 2: 37.5%
Option 3: 50%
Option 4: 87.5%
Correct Answer: 87.5%
Solution : Given: The cost price is INR 20 per kg. The selling price is INR 30 per kg. So, the profit percentage if he sold 1 kg $=\frac{10}{20}\times 100 = 50$% Now, the gain as a result of the incorrect weight: $=\frac{\text{Error}}{\text{True weight – Error}}\times 100$ $=\frac{200}{1000 – 200}\times 100$ $=\frac{200}{800}\times 100$ $= 25$% The actual profit percentage: $=P_{1}+P_{2}+\frac{P_{1}\times P_{2}}{100}$ $=50 + 25 + \frac{50\times 25}{100}$ $=75 + 12.5$ $=87.5$% Hence, the correct answer is 87.5%.

Question : Directions: In a certain code language, MADRAS is written as 112 and JAMMU is written as 82. How will PUNJAB be written in that language?
Option 1: 109
Option 2: 104
Option 3: 112
Option 4: 115
Correct Answer: 104
Solution : Given: MADRAS is written as 112 and JAMMU is written as 82.
Add the reverse position values of the letters of the word MADRAS then add the total number of letters in the word to obtain the required code – M→14; A→26; D→23; R→9; A→26; S→8 Now, add the reverse position values of the word MADRAS then add the total number of letters in the word – 14 + 26 + 23 + 9 + 26 + 8 = 106 + 6 = 112 Thus, MADRAS is coded as 112. And, JAMMU is written as 82 – J→17; A→26; M→14; M→14; U→6 Now, add the reverse position values of the word JAMMU then add the total number of letters in the word – 17 + 26 + 14 + 14 + 6 = 77 + 5 = 82 Thus, JAMMU is coded as 82. Similarly, follow the same pattern for PUNJAB – P→11; U→6; N→13; J→17; A→26; B→25 Now, add the reverse position values of the word PUNJAB then add the total number of letters in the word – 11 + 6 + 13 + 17 + 26 + 25 = 98 + 6 = 104
So, PUNJAB is coded as 104. Hence, the second option is correct.
Question : An airplane goes 14 km due east and then 48 km due north. How far is it from its initial position?
Option 1: 14 km
Option 2: 48 km
Option 3: 50 km
Option 4: 28 km
Correct Answer: 50 km
Solution : By Pythagoras theorem, $(AC)^2 = (AB)^2+(BC)^2$ ⇒ $(AC)^2=(14)^2 + (48)^2$ ⇒ $(AC)^2 = 196+ 2304$ ⇒ $AC = \sqrt{2500}$ ⇒ $AC = 50\ \mathrm{km}$ Hence, the correct answer is 50 km.
