Question : Hailstorms are caused due to
Option 1: Condensation
Option 2: Convection
Option 3: sublimation
Option 4: Freezing
Correct Answer: Freezing
Solution : The correct option is Freezing.
Hailstorms are caused by updrafts in thunderstorms that carry raindrops into extremely cold cloud areas where they come into touch with supercooled water droplets (liquid water below the freezing point). When the supercooled water droplets come into touch with the bigger raindrops, a phenomenon known as nucleation may occur. Tiny ice pellets are formed during this freezing process. The hailstones eventually hit the earth when they are too heavy for the updrafts to support.
Question : Directions: Select the correct mirror image of the given figure when the mirror is placed on the right side of the figure.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear close to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on line AB). So, the left side of the reflected image will appear as the right side, and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same. Thus, the correct mirror image of the given figure will be –
Hence, the fourth option is correct.
Question : In which year was the Estimates Committee constituted for the first time in India?
Option 1: 1948
Option 2: 1950
Option 3: 1947
Option 4: 1949
Correct Answer: 1950
Solution : The correct answer is 1950.
On the recommendation of the then-finance minister, John Matthai, the first Estimates Committee was formed in the post-independence era in 1950. It began with 25 members, but in 1956, the number was increased to 30. The committee's role was to review the budget forecasts and advise 'economies' in government spending.
Question : Directions: Select the correct combination of mathematical signs to sequentially replace the * signs and balance the given equation. 76 * 4 * 26 * 13 * 9 * 62
Option 1: –, +, ÷, ×, =
Option 2: +, ÷, ×, –, =
Option 3: +, –, ÷, ×, =
Option 4: ÷, –, +, ×, =
Correct Answer: +, –, ÷, ×, =
Solution : Given: 76 * 4 * 26 * 13 * 9 * 62
Replace the * sign given in the equation with the assigned signs in the options. Let's check the options –
First option: –, +, ÷, ×, = ⇒ 76 – 4 + 26 ÷ 13 × 9 = 62 Solving the L.H.S. of the equation – = 76 – 4 + 2 × 9 = 76 – 4 + 18 = 90 ≠ 62 Second option: +, ÷, ×, –, = ⇒ 76 + 4 ÷ 26 × 13 – 9 = 62 Solving the L.H.S. of the equation – = 76 + 0.153 × 13 – 9 = 76 + 1.98 – 9 68.98 ≠ 62 Third option: +, –, ÷, ×, = ⇒ 76 + 4 – 26 ÷ 13 × 9 = 62 Solving the L.H.S. of the equation – = 76 + 4 – 2 × 9 = 76 + 4 – 18 = 62 = R.H.S. Fourth option: ÷, –, +, ×, = ⇒ 76 ÷ 4 – 26 + 13 × 9 = 62 Solving the L.H.S. of the equation – = 19 – 26 + 117 = 110 ≠ 62
So, only the third option satisfies the equation. Hence, the third option is correct.

Option 1: control
Option 2: gesture
Option 3: source
Option 4: symbol
Correct Answer: source
Solution : The correct choice is the third option.
Explanation: A source is a place from which something originates. This helps convey the intended meaning that the Sun is the most important place from where the energy originates for life on Earth.

Question : Find the area of the shaded portion of an equilateral triangle with sides 6 units shown in the following figure. A circle of radius 1 unit is centred at the midpoint of a side of the triangle.
Option 1: $\frac{1}{2}\left(9 \sqrt{3}-\frac{11}{7}\right)$ unit$^2$
Option 2: $\frac{1}{4}\left(9 \sqrt{3}-\frac{11}{7}\right)$ unit $^2$
Option 3: $\frac{1}{2}\left(6 \sqrt{3}-\frac{11}{7}\right)$ unit$^2$
Option 4: $\frac{1}{2}\left(9 \sqrt{3}-\frac{22}{7}\right)$ unit$^2$
Correct Answer: $\frac{1}{2}\left(9 \sqrt{3}-\frac{11}{7}\right)$ unit$^2$
Solution : Area of equilateral triangle = $\frac{\sqrt 3}{4}(side)^2$ $= \frac{\sqrt3}{4}(6)^2 = 9\sqrt{3}\ \mathrm{unit}^2$ Area of circle = $\pi r^2 = \pi\ \mathrm{unit^2}$ where $r$ = radius of circle = 1 unit. Area of shaded region = $\frac{1}{2}$ Area of triangle - $\frac{1}{4}$ Area of circle Area of shaded region = $\frac{9\sqrt{3}}{2} - \frac{\pi}{4}$ $= \frac{9\sqrt{3}}{2} - \frac{22}{7\times 4}$ $= \frac{9\sqrt{3}}{2} - \frac{11}{7\times 2}$ $= \frac{1}{2}\left(9 \sqrt{3}-\frac{11}{7}\right)$ Hence, the correct answer is $\frac{1}{2}(9 \sqrt{3}-\frac{11}{7})$ unit2.
