not sufficient.
b) If statement (B) alone is sufficient to answer the question but statement (A) alone is
not sufficient.
c) If the two statements taken together are sufficient to answer the question, but neither
statement alone is sufficient
d) If each statement alone is sufficient to answer the question
e) If the two statements taken together are still not sufficient to answer the question.

1 Answer

Answer :

Using (A), we can have ‘p’ as 2/4/6/8 etc. we cant determine remainder when divided
by 3.
Using (B), we can have ‘p’ as 1/4/9/16 etc. we cant determine remainder when divided
by 3.
Using both ‘p’ is the square of an even number. So ‘p’ can be 4/16/36 etc.
We see that remainder can again be 1/0 (4/16 leave remainder 1, 36 remainder 0).
So, we cant determine using both statements.

A wire can be bent to form a circle of radius 56 cm. if it is instead bent in the form of a square, then its area will be: a) 6400 sq.cm b) 2025 sq.cm c) 7744 sq.cm d) 6561 sq.cm e) none of these

Description : A wire can be bent to form a circle of radius 56 cm. if it is instead bent in the form of a square, then its area will be: a) 6400 sq.cm b) 2025 sq.cm c) 7744 sq.cm d) 6561 sq.cm e) none of these

Last Answer : Length of the wire = circumference of the circle 2 × (22/7) × 56 = 2 × 22 × 8 = 352 cm side of square = 352/4 = 88cm area of square = 88 × 88 = 7744 sq.cm Answer: c)

A copper wire is bent to form an equilateral triangle of area 16√3 sq.cm. What will be the area (in sq.cm) if the same copper wire was bent to form a square? a) 16 b) 24 c) 32 d) 40 e) None of the above

Description : A copper wire is bent to form an equilateral triangle of area 16√3 sq.cm. What will be the area (in sq.cm) if the same copper wire was bent to form a square? a) 16 b) 24 c) 32 d) 40 e) None of the above

Last Answer : Area of equilateral triangle = 16√3 = √3 (side)2 /4 Or side2 = 16×4 = 64 So each side = 8cm Perimeter = 8×3 = 24 cm Since perimeter of the square is 24 cm, each side = 6cm So area = 6×6 = 36 sq cm Answer: e)

Cost of fencing a circular plot at the rate of Rs.15 per metre is Rs.3, 300. What will be the cost of flooring the plot at the rate of Rs.100 per square metre? a) Rs.3, 85,000 b) Rs.4, 70,000 c) Rs.2, 25,000 d) Rs.3, 50,000 e) Rs.2, 95,000

Description : Cost of fencing a circular plot at the rate of Rs.15 per metre is Rs.3, 300. What will be the cost of flooring the plot at the rate of Rs.100 per square metre? a) Rs.3, 85,000 b) Rs.4, 70,000 c) Rs.2, 25,000 d) Rs.3, 50,000 e) Rs.2, 95,000

Last Answer : Perimeter of plot = 3300/15 = 220 meter 2πr = 220 2 × 22/7 × r = 220 r = 35 m. Area of plot = πr^2 = 22/7 × 35 × 35 = 3850 mt^2 Cost of flooring = 3850 × 100=Rs. 385000 Answer: a)
