The Organisation for the Prohibition of Chemical Weapons (OPCW) is not a company but an intergovernmental organization responsible for implementing the Chemical Weapons Convention (CWC), which aims to eliminate the production, stockpiling, and use of chemical weapons. Established in 1997 and based in The Hague, Netherlands, the OPCW has been instrumental in overseeing the global disarmament efforts against chemical weapons.
With 193 member states, the OPCW operates as an independent body, conducting inspections, verifying declarations from member states, and promoting international cooperation in the peaceful use of chemistry. Its work involves conducting investigations into alleged uses of chemical weapons and assisting member states in strengthening their chemical safety and security measures.
The OPCW gained significant attention for its role in the disarmament of Syria's chemical weapons stockpile, following the deadly sarin gas attack in Ghouta in 2013. Its efforts have contributed to a significant reduction in the global stockpiles of chemical weapons, enhancing global security and stability.
The organization operates through a system of inspections, laboratory analyses, and diplomatic negotiations, adhering strictly to principles of impartiality, transparency, and technical expertise. Its work remains crucial in preventing the proliferation of chemical weapons and promoting a world free of the threat posed by these devastating weapons of mass destruction.
The work done by A in 8 days is = 8/ 12 = 2/3
Means A alone completes 2/3 part of work.
Remaining work which is (1–2/3) = 1/3 is completed by B in 8–2 = 6 days
So the complete work done by B in 6/(1/3) = 18 days.
B alone can complete the work in 18 days.

A=3*9=27Rs
B=7*15=105Rs
132 R for 10 kg
therefore,
1kg amount = 132/10=13.2 so,
5kg mixture price = 13.2*5=66Rs
mixture will sell 25%profit then the price =66*(25/10)=33/2=16.5Rs

When A runs 1000 meters, B runs 900 meters and when B runs 800 meters, C runs 700 meters.
Therefore, when B runs 900 meters, the distance that C runs = (900 x 700)/800 = 6300/8 = 787.5 meters.
So, in a race of 1000 meters, A beats C by (1000 – 787.5) = 212.5 meters to C.
So, in a race of 600 meters, the number of meters by Which A beats C = (600 x 212.5)/1000 = 127.5 meters.
Suppose 1 person consumes 1 unit food daily.
So, for 24 days, 1600 person will consume 1600×24 units.
So total units of food available = 1600×24
Now total number of person =1200
So, total food will be consumed by 1200 person in (1600×24)/1200 = 32 days.

Out of 10 persons, 4 are graduates; so, (10 – 4) = 6 are under-graduates.
If there is no restriction, any three can be chosen from the ten in (10C3) = 120 ways.
Now, if all three chosen are under-graduates; it can take place in (6C3) = 20 ways.
Therefore, the probability that there will be no graduate among the three chosen = (20 / 120) = (1 / 6).
Therefore, the probability that there will be at least one graduate among the three chosen = {1 – (1 / 6)} = (5 / 6) = 0.8333.
temp at 3.oo pm is = 22.5
temp at 6.oo pm is = 30
thus, percentage rise= 7.5/30 *100
=25%
