- Direct material consumed: Rs. 90,000
- Direct labour: Rs. 60,000
- Direct expenses: Rs. 20,000
- Manufacturing overheads: Rs. 30,000

From the following information, find out the number of units that must be sold by the firm to earn a profit of Rs. 1,80,000 per year:

- Sales price: Rs. 25 per unit
- Variable manufacturing costs: Rs. 12 per unit
- Variable selling costs: Rs. 3 per unit
- Fixed factory overheads: Rs. 5,00,000
- Fixed selling costs: Rs. 3,00,000

Explanation

Contribution per unit = Selling Price - Total Variable Cost = 25 - (12 + 3) = Rs. 10. Total Fixed Cost = 5,00,000 + 3,00,000 = Rs. 8,00,000. Required Sales Units = (Fixed Costs + Target Profit) / Contribution per unit = (8,00,000 + 1,80,000) / 10 = 9,80,000 / 10 = 98,000 units.

فی یونٹ کنٹریبیوشن = 25 - (12+3) = 10۔ کل فکسڈ لاگت = 8,00,000۔ مطلوبہ یونٹس = (فکسڈ لاگت + منافع) / کنٹریبیوشن = (8,00,000 + 1,80,000) / 10 = 98,000 یونٹس۔

Explanation

Sum of age of 4 persons 4 years ago = 4 18 = 72 years. Today, their age sum increases by 4 4 = 16 years, making it 88 years. Today, there are 5 family members and their average age is 18, so total sum = 5 * 18 = 90 years. Baby's age = 90 - 88 = 2 years.

چار سال پہلے 4 افراد کی کل عمر = 4 * 18 = 72 سال۔ آج ان کی کل عمر = 72 + 16 = 88 سال ہوگی۔ اب خاندان میں 5 افراد ہیں اور اوسط عمر اب بھی 18 سال ہے، یعنی کل عمر = 90 سال۔ بچے کی عمر = 90 - 88 = 2 سال ہے۔

Read the following passage carefully to answer the question:

"In an era marked by environmental concerns and the urgent need for action against climate change, sustainable energy has emerged as a beacon of hope. Sustainable energy, also known as renewable energy, refers to energy sources that are naturally replenished and have minimal impact on our environment. The various energy sources are solar, wind, hydroelectric, geothermal, and biomass. The adoption of sustainable energy holds immense promise in addressing some of the most pressing challenges facing humanity today. One of its primary goals is to reduce dependence on finite fossil fuels, such as coal, oil, and natural gas, which contribute significantly to greenhouse gas emissions and air pollution. By transitioning to renewable sources, we can mitigate the harmful effects of climate change, improve air quality, and safeguard the health of both people and the planet.

Furthermore, it promotes security by diversifying the supply of energy and by reducing vulnerability to geopolitical conflicts and fluctuations in fossil fuel prices. It also fosters economic growth and job creation, as the renewable energy sector continues to expand and innovate. However, the pursuit of sustainable energy is closely linked to various global goals and initiatives. The United Nations Sustainable Development Goals (SDGs), emphasize the importance of ensuring access to reliable, sustainable, and modern energy for all. Additionally, the Paris Agreement aims to limit the increase in the global average temperature to well below 2°C above pre-industrial level. Governments, businesses, and individuals must work together to accelerate the transition to sustainable energy. This involves investing in research and development, implementing supportive policies and regulations, enhancing energy efficiency, and promoting public awareness and education."

This period was divided into the Paleolithic, Mesolithic and Neolithic periods. During the First Age (2 million to 8000 BC), the first hatchets and the use of fire for heating and cooking were developed.

As a result of the Ice Age, which evolved about 1 million years into the Paleolithic era, humans were forced to shelter in caves, wear clothing, and develop new tools. During the Mesolithic period (8000 to 6000 BC), people made crude pottery and took dogs for hunting with the first fish hook and developed a bow and arrow, which was used until the fourteenth century BC. The Neolithic period (6000 to 3000 BC) saw mankind domesticating sheep, goats, pigs and cattle, becoming less nomadic than in earlier periods, establishing permanent settlements and forming governments."

. Since

V_{cube} = V_{sphere}

, the ratio of solidification times is

\frac{t_{cube}}{t_{sphere}} = \left(\frac{A_{sphere}}{A_{cube}} ight)^2 = \left(\frac{4\pi r^2}{6 l^2}\right)^2 = \left(\frac{4\pi}{6}\right)^2 \left(\frac{r}{l}\right)^4

539📚Radiation Detection & DosimetrySLD Repair & Cell Cycle Reassortment

The increase of cell survival because of sublethal damage repair:

Explanation

As time increases between split doses, surviving synchronized cells progress around the cell cycle and enter more sensitive phases (M/G2 - reassortment), which produces a dip in survival that counteracts pure repair.

सब-लीथल मरम्मत द्वारा उत्तरजीविता में वृद्धि कोशिका चक्र में आगे बढ़ने ('पुनर्वर्गीकरण' / Reassortment) के कारण संवेदनशीलता बढ़ने से प्रभावित/बाधित होती है।
