Question : S, T, and U can complete a work in 40, 48, and 60 days, respectively. They received Rs. 10,800 to complete the work. They began the work together, but T left 2 days before the completion of the work and U left 5 days before the completion of the work. S has completed the remaining work alone. What is the share of S (in Rs.) from the total money?
Option 1: 4000
Option 2: 4320
Option 3: 4500
Option 4: 4860
Correct Answer: 4860
Solution : S’s 1 day work =$\frac{1}{40}$ T’s 1 day work = $\frac{1}{48}$ U’s 1 day work = $\frac{1}{60}$ Let the work be completed in $x$ days, such that S worked for all $x$ days, T worked for $(x - 2)$ days, and U for $(x -
Question : ΔABC and ΔDEF are congruent respectively. If AB = 6 = DE, BC = 8 = EF and $\angle$B = 30°, then $\angle$D + $\angle$C _________.
Option 1: 160°
Option 2: 120°
Option 3: 130°
Option 4: 150°
Correct Answer: 150°
Solution : Given, that $\triangle$ABC and $\triangle$DEF are congruent. AB = 6 = DE, BC = 8 = EF, and $\angle$B = 30° Since, $\triangle$ABC $\cong$ $\triangle$DEF ⇒ $\angle$A = $\angle$D By angle sum property in $\triangle$ABC, $\angle$A + $\angle$B + $\angle$C = 180° ⇒ $\angle$D +
Question : Direction: Read the following passage and answer the questions given after it. The science of climate change is more solid and widely agreed upon than you might think. But the scope of the topic, as well as rampant disinformation, can make it hard to separate fact from fiction. Here, we've done our best to present you with not only the most accurate scientific information but also an explanation of how we know it. Climate change is often cast as a prediction made by complicated computer models. But the scientific basis for climate change is much broader, and models are actually only one part of it (and, for what it's worth, they're surprisingly accurate).
For more than a century, scientists have understood the basic physics behind why greenhouse gases like carbon dioxide cause warming. These gases make up just a small fraction of the atmosphere but exert outsized control on Earth's climate by trapping some of the planet's heat before it escapes into space. This greenhouse effect is important: It's why a planet so far from the sun has liquid water and life! However, during the Industrial Revolution, people started burning coal and other fossil fuels to power factories, smelters and steam engines, which added more greenhouse gases to the atmosphere. Ever since human activities have been heating the planet.
