Yuvraj Singh was the Player of the Tournament in ICC Cricket World Cup 2011, scoring 362 runs and taking 15 wickets. His all-round performance was instrumental in India's World Cup victory.

Dandiya or Dandia is a traditional folk dance form originating from Gujarat, performed during the Navratri festival. It involves paired dancers striking bamboo sticks (dandiyas) in rhythmic patterns.

If 40% of apples are sold, 60% remain = 300 apples. So 0.6x = 300, giving x = 500 original apples. Since 500 is not listed in options A-C (800, 600, 700), 'None of these' is correct.

Cost price per toffee = 1/6 rupee. For 20% profit, selling price must be 1.20 × cost = 1.20 × (1/6) = 0.20 rupee per toffee. At 20 paise each, he sells 5 toffees for a rupee (5 × 0.20 = 1.00 rupee).

Since x% of y means (x/100) × y = xy/100, and y% of x means (y/100) × x = xy/100, both expressions simplify to the same value. Therefore A equals B regardless of the values of x and y.

The Lokpal Bill was indeed stalled for decades since its introduction around 1968, and has been in and out of news over the years depending on political developments. However, the accuracy of this answer depends on when exactly this question was framed.

Let Johnny's current age be x. Then father's age is 4x (three times more than x, not three times x). After 8 years: (4x+8)/(x+8) = 2.5, which gives x = 8. After 16 more years (total 24 years later): father = 48, Johnny = 24, so father is 2 times Johnny's age.

In first 10 overs at 3.2 run rate: 10 × 3.2 = 32 runs scored. Remaining runs needed: 282 - 32 = 250 runs in 40 overs. Required run rate = 250/40 = 6.25 runs per over.

Train speed = 54 km/hr = 15 m/sec. In 20 sec, train passes a man, so train length = 15 × 20 = 300 m. In 36 sec, train passes platform, so train + platform length = 15 × 36 = 540 m. Platform length = 540 - 300 = 240 m.

Let Rita's age = x. Geeta = 2x. Seeta = 2x + 4. Total: x + 2x + 2x + 4 = 54, so 5x = 50, x = 10. Geeta's age = 2x = 20 years. Note: the question spells Reeta inconsistently.

To keep the average of 20 numbers at zero, the sum must be zero. You can have 19 positive numbers as long as the 20th number is a negative value equal to the sum of the others. You cannot have 20 positive numbers because their sum would exceed zero.

Let marks be x and x+30. Higher score = 60% of sum, so x+30 = 0.60(2x+30). Solving: x+30 = 1.2x + 18, so 12 = 0.2x, x = 60. The marks are 60 and 90, which is option B.

Trains approach at combined speed 40 + 60 = 100 km/h. Distance 500 km takes 5 hours to meet. Bird flies for 4 hours (one hour before meeting). Distance = 10 × 4 = 40 km.

Nobel Prizes are consistently awarded on December 10th every year, commemorating the anniversary of Alfred Nobel's death in 1896. The ceremony takes place in Stockholm, Sweden and Oslo, Norway.

The Scandinavian coasts have many raised sea beaches which lie from 8 metres to 30 metres above present day sea level. These are evidence of post-glacial rebound - the land rising after the weight of ice sheets melted. The exact measurements vary, but 8-30 metres is the commonly cited range in geographical studies.

Oxidation, carbonation, hydrolysis, and solution are all chemical weathering processes. These involve chemical reactions that break down rocks and minerals through processes like oxygen reacting with minerals (oxidation), carbon dioxide dissolving in water (carbonation), water reacting with minerals (hydrolysis), and minerals dissolving in water (solution). Biological weathering involves living organisms, while physical weathering involves mechanical breakdown.

Caves, arches, and stacks are erosional features formed by wave action along coastlines. Waves continuously erode weaknesses in rock headlands, eventually forming caves that extend through to become arches, which then collapse to leave isolated stacks. Wind and glaciers create different landforms, and running water creates valleys and canyons rather than these coastal features.

Hot springs and geysers are common in all three locations: Iceland, North Island of New Zealand, and Yellowstone National Park in the USA. All these areas sit on active geothermal regions with volcanic activity that heats underground water, which then erupts at the surface as hot springs or geysers.

The Dead Sea surface is approximately 393 meters below sea level according to this question's data. The Dead Sea, bordered by Jordan and Israel, is the lowest point on Earth's land surface. The depth from surface to floor being 819m means the water body is about 426m deep (819-393). The other options (439m, 493m, 339m) don't match the approximate elevation of the Dead Sea surface.
