Question : In the context of mapping climate data, what term refers to a line drawn through all points on a map that contain the same amount of cloud?
Option 1: Isohels
Option 2: Isocheim
Option 3: Isonephs
Option 4: Isochalaz
Correct Answer: Isonephs
Solution : The correct option is Isonephs.

Question : A solid metallic sphere of radius 13 cm is melted and recast into a cone having a diameter of the base as 13 cm. What is the height of the cone?
Option 1: 246 cm
Option 2: 152 cm
Option 3: 174 cm
Option 4: 208 cm
Correct Answer: 208 cm
Solution : We know, The volume of a cone = $\frac{1}{3}πr^2h$, where r is the radius of the cone The volume of a sphere = $\frac{4}{3}πR^3$, where r is the radius of the sphere According to the question, $\frac{4}{3}πR^3 = \frac13πr^2h$ Let the height of the
Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given set. (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) (32, 24, 8) (48, 42, 6)
Option 1: (64, 62, 8)
Option 2: (56, 50, 6)
Option 3: (16, 14, 4)
Option 4: (18, 12, 4)
Correct Answer: (56, 50, 6)
Solution : Given: (32, 24, 8); (48, 42, 6) The pattern is – (32, 24, 8)→32 – 24 = 8 (48, 42, 6)→48 – 42 = 6
Let's check each option – First option: (64, 62, 8) = 64 – 62 = 2 ≠ 8
Question : Directions: In the following question, select the number that can be placed at the sign of the question mark (?) from the given alternatives.
Option 1: 54
Option 2: 60
Option 3: 62
Option 4: 66
Correct Answer: 66
Solution : Add the multiplication of numbers given in diagonal blocks, to get the number of centre blocks.
In the first figure – (4 × 3) + (5 × 2) = 12 + 10 = 22 In the second figure – (1 × 2) + (7
Question : A vessel contains 20 L of acid. 4 L of acid is taken out of the vessel and replaced by the same quantity of water. Next, 4 L of the mixture is withdrawn and again the vessel is filled with the same quantity of water. The ratio of the quantity of acid left in the vessel with the quantity of acid initially in the vessel is:
Option 1: 4 : 5
Option 2: 4 : 25
Option 3: 16 : 25
Option 4: 1 : 5
Correct Answer: 16 : 25
Solution : Here, Remaining acid = Initial quantity × $(1–\frac{\text{Quantity taken out}}{\text{Original quantity}})^{\text{number of times removed}}$ ⇒ Remaining acid $=20×(1-\frac{4}{20})^2=20×\frac{4}{5}×\frac{4}{5}= 12.8$ L So, the required ratio = (12.8) : (20) = 128 : 200 = 16 : 25 Hence, the correct answer is 16 :
Question : Directions: Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation. 55 * 63 * 9 * 8 * 3 = 38
Option 1: ÷, ×, –, +
Option 2: ×, ÷, +, –
Option 3: +, –, ×, ÷
Option 4: +, ÷, –, ×
Correct Answer: +, ÷, –, ×
Solution : Given: 55 * 63 * 9 * 8 * 3 = 38
Let's check the given options – First option: ÷, ×, –, + ⇒ 55 ÷ 63 × 9 – 8 + 3 = 38 Solving the L.H.S. of the equation

Question : The selling price and the cost price of a cup are INR 576 and INR 800 respectively. What is the loss percentage?
Option 1: 22%
Option 2: 28%
Option 3: 24%
Option 4: 32%
Correct Answer: 28%
Solution : Selling price = INR 576 Cost price = INR 800 Loss = Cost price – selling price = 800 – 576 = 224 Loss percentage = $\frac{\text{Loss}}{\text{Cost price}}\times100= \frac{224}{800}\times100= 28$% Hence, the correct answer is 28%.
Question : The monthly salary of a person was INR 75,000. He used to spend on Family Expenses (E), Taxes (T), and Charity (C), and the rest was his savings. E was 60% of the income, T was 20% of E and C was 15% of T. When his salary was raised by 40%, he maintained the percentage level of E, but T became 30% of E and C became 20% of T. The ratio of the savings of his earlier salary to that of his present salary is:
Option 1: 655 : 644
Option 2: 325 : 337
Option 3: 644 : 655
Option 4: 337 : 325
Correct Answer: 655 : 644
Solution : Savings = Income − (E + T + C) E = 0.60 × 75000 = 45000 T = 0.20 × 45000 = 9000 C = 0.15 × 9000 = 1350 Now, savings = 75000 − (45000 + 9000 + 1350) = 19650 When
