  • Question 1/10
    1 / -0
    In the following question below are given some statements followed by some conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements.

    Statements:
    I. Some Shriesh is Shreya.
    II. Some Shriesh is Ram.

    Conclusions:
    I. All Ram can be Shreya.
    II. Some Shreya can be Shriesh.
    III. Some ram is Shriesh.

    Solutions

    The least possible Venn - diagram is:

    I. All ram can be Shreya – Here possibility holds true, hence follows.

    II. Some Shreya can be Shriesh – Since it is already given in the statement hence it is the definite condition, so the possibility can't hold true here, hence false.

    III. Some Ram is Shriesh – It is a definite case, hence true.

    So, the conclusion I and III follow.

    Hence, option C is the correct answer.

    1 / -0
    Evaluate : sin 75°
    Solutions
    ⇒ Sin 75° = Sin (45° + 30°)
    ⇒ Sin 45° × cos 30° + sin 30° × cos 45°

    ⇒           

    ⇒
