Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (6, 8, 106) (7, 11, 177)
Option 1: (8, 7, 119)
Option 2: (9, 8, 154)
Option 3: (5, 9, 101)
Option 4: (7, 9, 136)
Correct Answer: (9, 8, 154)
Solution : Given: (6, 8, 106); (7, 11, 177)
Like, (6, 8, 106)→(6)2 + (8)2 + 6 = 36 + 64 + 6 = 106 (7, 11, 177)→(7)2 + (11)2 + 7 = 49 + 121 + 7 = 177

Question : The cliff of a mountain is 180 m high and the angles of depression of two ships on either side of the cliff are 30° and 60°. What is the distance between the two ships?
Option 1: $400$ metres
Option 2: $400\sqrt{3}$ metres
Option 3: $415.68$ metres
Option 4: $398.6$ metres
Correct Answer: $415.68$ metres
Solution : AD = Cliff = 180 metres $\angle$ABD = 60°, $\angle$ACD = 30° From ∆ABD, $\tan 60° = \frac{AD}{BD}$ ⇒$\sqrt{3}=\frac{180}{BD}$ $\therefore BD=60\sqrt{3}$ metres From ∆ACD, $\tan 30° = \frac{AD}{CD}$ ⇒ $\frac{1}{\sqrt{3}}=\frac{180}{CD}$ $\therefore CD=180\sqrt{3}$ metres ∴ BC = BD + DC $\therefore BC=60\sqrt{3}+180\sqrt{3} =240\sqrt{3}=(240 × 1.732)=
Question : The total surface area of a hemisphere is 462 cm2. The diameter of this hemisphere is:
Option 1: 28 cm
Option 2: 21 cm
Option 3: 7 cm
Option 4: 14 cm
Correct Answer: 14 cm
Solution : Here, the total surface area of a hemisphere = 462 cm2 ⇒ $3\pi r^2 = 462$ ⇒ $ 3 \times \frac{22}{7} \times r^2= 462$ ⇒ $r^2= 49$ ⇒ $ r = 7$ cm $\therefore$ Diameter of the hemisphere $= 2r = 2 \times
Question : A mixer marked at Rs. 2,300 is sold for Rs. 2,024. What is the percentage of discount?
Option 1: 13%
Option 2: 10%
Option 3: 12%
Option 4: 11%
Correct Answer: 12%
Solution : Given, A mixer marked at Rs. 2,300 is sold for Rs. 2,024 Discount = Marked price - Selling price = 2300 – 2024 = Rs. 276 Now, discount percentage = $(\frac{\text{Discount}}{\text{Marked price}}) × 100$ = $\frac{276}{2300} × 100$ = 0.12 × 100 = 12% Hence,
