  • Question 1/12
    1 / -0
    Select the related word/letters/ number from the given alternatives.

    9 : 80 :: 100 : ?
    Solutions
    As (9 : 80) 
    92 - 1 = 81 - 1 = 80
    Similarly, (100 : ?)
    ? = 1002 - 1 = 10000 - 1 = 9999

    Hence, option (D) is the correct response.
  • Question 2/12
    1 / -0

    1 / -0

    If January 1st is a Friday, what is the first day of the month of March in a leap year?

    Solutions

    If the first January is Friday then the first February would be Monday.
    29th February => Monday
    Therefore;
    1st March => Tuesday.
    Hence Option C is correct

  • Question 4/12
    1 / -0
    What is the normal temperature of the human body?
    Solutions
    • The average normal body temperature is 98.6°F (37°C).
    • It is typically maintained within 36.5-37.5°C range by thermoregulation, however it depends on a lot of other factors.
    • Basal body temperature is the lowest temperature attained by the body during rest.
  • Question 5/12
    1 / -0
    Which of the following parts of human body is affected by Pyria?
    Solutions
    • Pyria is ususally a symptom of poor dental hygiene, where the person is not brushing often, or not adequately enough leading to bacteria growth in and around the gums.

  • Question 7/12
    1 / -0
    A ship is moving at a speed or 30 km/hr. To know the depth of the ocean beneath it, it sends a radio wave which travels at a speed 200 m/s. The ship receives the signal after it has moved 500 m. The depth of the ocean is
    Solutions
    Ship sends a radio wave at a speed of 200m/s from the point O and move forward with a speed 30 km/ hr
    Speed of boat = 30 × 1000/ 60 × 60 = (25/3) m/s
    Ship received the signal at point Q, where OQ = 500m

    Let radio wave reflects from point P, hence depth of ocean = OP
    Therefore time taken by ship to travel OQ = time taken by radio wave to travel OP then PQ
    Hence time t = distance / speed = 500/ (25/3) = 60 sec
    Hence distance travelled by radio wave in 60 sec = speed × time
    = 200×60 = 12000 m
    Hence OP+PQ = 12000m = 12km
    Let OP = X km
    PQ = (12– X)km
    By Pythagoras theorem
  • Question 8/12
    1 / -0
    The point equidistant from the sides of a triangle is called _______. 
    Solutions
    The point equidistant from the sides of a triangle is called Incentre. It is the point of intersection of angular bisectors.

    A circumcenter is a point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices

    An orthocenter is one of the triangle's points of concurrency formed by the intersection of the triangle's 3 altitudes. These three altitudes are always concurrent. In other, the three altitudes all must intersect at a single point, and we call this point the orthocenter of the triangle.

     A centroid is formed by the intersection of the medians. It is one of the points of concurrency of a triangle.
  • Question 9/12
    1 / -0
    A circle of radius 6.5 cm has a diameter AB. C is a point on the circle such that AC < BC. If length of AC = 5cm, find the area of ∆ ABC.
    Solutions

    ⇒ Since angle in semi-circle in always 900
    ⇒ ∴AB2 = AC2 + BC2
    ⇒ AB = 6.5×2 = 13
    ⇒ AC = 5 cm
    ⇒ ∴BC = 12 cm
    ⇒ Area = 1/2×AC×BC 
    ⇒ Area = 1/2×12×5 
    ⇒ Area = 30 cm2

    She was beside herself in joy when she came to know that she had been selected for the job.
    Solutions
    Option C is correct.
    The sentence has a prepositional error. The use of the preposition "in" is incorrect here and should be replaced by "with". Beside oneself is a phrase which means overcome with worry, grief, or anger; distraught. When a noun is used after it, the preposition "with" is used. See example:
    He was beside himself with anger.
