उत्तर : 4. "Indeterminate"
व्याख्या :
Answer: D) Indeterminate Explanation: Indeterminate are those,which mathematics can’t determine. Because we don’t actually know which one is the exact answer for this due to having lots of results for this. Explanation:: Let us think by this analogy that, 0 / 1 = 0 0 / 2 = 0 ………… ……….. we can say 0 / n = 0 from this we can write, 0/0 = 0 Again, another analogy,(from limiting concept of 1/0 = infinity) 1 / 0 = +∞ or -∞ 2 /0 = +∞ or -∞ ……… .……. we can say 0 / 0 = ∞ Again, another analogy, 1 / 1 = 1 2/2 = 1 .…….. ……….. we can say, 0/0 = 1 Now, you see it’s confusing. Every analog is mathematically correct then which one is the right answer for 0/0. Therefore Mathematics can’t determine this fact. So, 0/0 is indeterminate.

उत्तर : 4. "15"
व्याख्या :
Answer: D) 15 Explanation: Let 'K' be the total number of sweets.Given total number of students = 112If sweets are distributed among 112 children,Let number of sweets each student gets = 'L' => K/112 = L ....(1)But on that day students absent = 32 => remaining = 112 - 32 = 80Then, each student gets '6' sweets extra. => K/80 = L + 6 ....(2)from (1) K = 112L substitute in (2), we get112L = 80L + 48032L = 480L = 15 Therefore, 15 sweets were each student originally supposed to get.

प्र:Read the passage carefully and give the answer of following questions.
A glass bottle that is sent to a landfill can take up to a million years to break down. By contrast, it takes as little as 30 days for a recycled glass bottle to leave your kitchen recycling bin and appear on a store shelf as a new glass container. Glass container are 100 percent recyclable, which means they can be recyclable repeatedly, again and again, with no loss of purify or quality in the glass. Recovered glass from glass recycling is the primary ingredient in all new glass containers. A typical glass container is made of as much as 70 percent recycled glass. According to industry estimates, 80 percent of all recycled glass eventually ends up as new glass containers. Every ton of glass that is recycled save more than a ton of the raw materials needed to create new glass, including 13,00 pounds of sand, 410 pounds of soda ash, and 380 pounds of limestone.
Because glass is made from natural materials such as sand and limestones, glass containers have a low rate of chemical interaction with their contents. As a result, glass can be safety reused.
Besides serving as the primary ingredient in new glass containers, recycled glass also has many other commercial uses-from creating decorative tiles and landscaping materials to rebuilding eroded beaches.
