Directions to Solve

Each of these questions is followed by three statements. You have to study the question and all the three statements given to decide whether any information provided in the statement(s) is redundant and can be dispensed with while answering the given question.

What is the area of the given rectangle?
I.
Perimeter of the rectangle is 60 cm.
II.
Breadth of the rectangle is 12 cm.
III.
Sum of two adjacent sides is 30 cm.

[A].	I only
[B].	II only
[C].	I and II only
[D].	II and III only
[E].	II and either I or III

Answer: Option C

Explanation:

From I and II, we can find the length and breadth of the rectangle and therefore the area can be obtained.

So, III is redundant.

Also, from II and III, we can find the length and breadth and therefore the area can be obtained.

So, I is redundant.

Correct answer is "II and either I or III".

Perimeter of a rectangle is 2(L+B),as per 1st and 2nd statement Perimeter is 60cm and Breath is 12 cm then Perimeter=2(L+B) 60=2(L+12) L=(60/2)-12 L=18 now we can find the area of rectangle by using formula Area=LxB that is 12x18=216

In General perimeter of a rectangle is ] 1....2(l+b)=60; 2...b=12; 3...(l+b)=30; we cant get any l and b values by usign 1 an 2 statements we can get answer by taking 2 and either 1 or 3

If first and second is find then we also find area of wall because we know 2*(l+b)then l+b is given.

l+b=30 So perimeter=2(l+b)=2*30=60 i.e. given so only 1 and 3 rd is correct
