here u hav to add the degrees…I mean 10+70=80 degrees..(10E + 70W)
I wil tel u the simpler way of solvin this ques…..
Nw 80*4=320 mins( multiplied by 4 bcoz 1degree=4 min)den convert to hrs wch is 3hrs20min..
Nw the plane startd at 2 am n takes 10 hrs,,,so time dat it shud reach is 12noon,,
the point to b noted here is dat wen plane is moving frm EAST to WEST…u hav to subtract the
time taken(320mins)frm 12noon…
wch becomes 12noon – 320 mins=6:40 am
gotit??

6. Given $ means Tripling and % means change of sign then find the value of $%$6-%$%6
ans: -72
(($%$6)-(%$%6))
here..tripling means multiplyin by 3 …
so 6 is multiplied by 3 two times in first pair of brackets
bcoz of 2 dollar signs..
in second part its multiplied by 3 once ..
in 1st part
ie…6*3=18
18*3=54
Nxt it bcomes -54 bcoz of % sign ….so first part is -54
In 2nd part
Its -18…(6*3)
So the eq bcomes -54-18=72/// ans

Directions (Q. 11-25): Read the following passage carefully and answer the questions given below it. Certain words are given in bold to help you to locate them while answering some of the questions.

The health of nations can be measured by the food security and well-being of their people. An innovative programme in India shows how botanic gardens can contribute to that well-being by educating people about the uses of local biodiversity, particularly for healthcare and income-generation.
     In 1994, the Tropical Botanic Garden and Research Institute in Kerala launched two outreach programmes - “Herbs for All and Health for All” and “Plants for All and Wealth for All”. The programmes teach people how to take care of their food, nutrition, hygiene and health by making the best use of the plant resources around them.
     The Research Institute selected four rural villages as partners. A team of scientists, including botanists, experts in Ayurveda (a holistic system of healing, which evolved among the sages of India some 3000-5000 years ago), and sociologists visited the villages and met with local leaders to explain the programmes. The villages selected representatives to attend a two-day workshop in Kerala devoted to agro biodiversity and conservation.
     The workshop particularly highlighted the role of home gardens as a tool for the community management of genetic resources. The students visited a model home garden at the institute, composed of many different medicinal and ornamental plants and vegetables. They were encouraged to take samples from the home garden with them when they returned to their villages.
     The next step was intensive training on primary health care and the conservation and sustainable use of plant diversity. The trainees, a core group of 10 people selected from the workshop participants by each village, learned how to treat common ailments with plants conserved at the Botanic Garden.
     At the end of the training, they were furnished with seedlings of medicinal plants and lesser known fruits and vegetables, as well as practical information on cultivating them back home.
     Returning to their villages, the trainees each adopted 20 local families to educate in the preparation and use of plant-based herbal medicines, stressing the need for self-reliance in the primary health care of family members.
The programme has since been extended to other villages and the Botanic Garden and Research Institute has widened its reach even further by producing and distributing brochures, fliers and books in the local language on primary health care, commonly cultivated medicinal and aromatic plants and wild edible fruits and vegetables.
     The Kerala programme has been recognized by the World Bank and international organizations as an inspiration for projects in developing countries.
