    Human Diseases Caused by Fungi Fungal Diseases:
    1. Ringworm caused by Microsporum, Trichophyton by direct contact from unbathed cats and dogs or objects handled by infected individuals.
    2.Athlete's foot caused by Trichophyton by Bad foot hygiene
    where skin remains warm and moist for long period, fungi finds optimal condition, invade dead outer layer of skin.

    Human Diseases Caused by Viruses Viral Diseases:
    1. Smallpox caused by Variola Virus by direct contact
    (droplets), indirected by infected articles.
    2. Chicken pox caused by Varicella virus by direct contact (droplets) indirected by infected objects.
    3. Common cold caused by Rhinovirus by contact.
    4. Influenza/Flu caused by Orthomixovirus by contact (droplets) virus transmitted through discharge from respiratory tracts of persons infected with disease
    5. Mumps caused by Mumps virus by direct contact, virus in
    Saliva and secretion of nose invades salivary glands.
    6. Viral encephalitis caused by Encephalitis virus (arbovirus)

  2. If the base of a rectangle is increased by 10% and the area is unchanged, then the corresponding altitude must be decreased by :
    a. 100/11%
    b. 10%
    c. 11%
    d. 100/9%
    e. 12 %

    please explain anybody?

  3. let breadth=b
    since base increases by 10
    new base b'=1.1*b
    let altitute decreases by X%
    new length(altitute) l'=(100-x)/100*l
    new Area=l'*b'=(100-x)/100*l*1.1*b
    since area is unchanged
    new Area=l*b
