Question : If $x=p+\frac{1}{p}$ and $y=p-\frac{1}{p}$, then the value of $x^{4}-2x^{2}y^{2}+y^{4}$ is:
Option 1: 24
Option 2: 4
Option 3: 16
Option 4: 8
Correct Answer: 16
Solution : $x = p+\frac{1}{p}$ $y = p-\frac{1}{p}$ Now, $x^{4}-2x^{2}y^{2}+y^{4}$ = $(x^{2}-y^{2})^{2}$ = $((x+y)(x-y))^{2}$ = $[(p+\frac{1}{p}+p-\frac{1}{p})(p+\frac{1}{p}-(p-\frac{1}{p})]^{2}$ = $[2×p×2×\frac{1}{p}]^{2}$ = 16 Hence, the correct answer is 16.
Question : The average weight of three men A, B, and C is 84 kg. Another man, D joins the group and the average now becomes 80 kg. If another man, E whose weight is 3 kg more than that of D, replaces A, then the average weight of B, C, D, and E becomes 79 kg. Then the weight of A is:
Option 1: 72 kg
Option 2: 74 kg
Option 3: 75 kg
Option 4: 76 kg
Correct Answer: 75 kg
Solution : The average weight of three men A, B, and C is 84 kg. $\therefore$ The total weight of A, B, and C = 84 × 3 = 252 kg Now, D joins the group and the average now becomes 80 kg. $\therefore$ Weight of
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (16, 32, 54) (29, 58, 80)
Option 1: (17, 35, 59)
Option 2: (25, 50, 62)
Option 3: (24, 48, 70)
Option 4: (23, 46, 62)
Correct Answer: (24, 48, 70)
Solution : Given: (16, 32, 54); (29, 58, 80)
In the given sets, multiply the first number by 2 to get the second number and then add 22 to the second number to obtain the third number. (16, 32, 54)→16 × 2 = 32; 32
Question : A wire is in the form of a square with a side of 11 cm. It is bent to form a circle. What is the radius of the circle?
Option 1: 11 cm
Option 2: 5 cm
Option 3: 9 cm
Option 4: 7 cm
Correct Answer: 7 cm
Solution : Side of square = 11 cm Perimeter of square = 4 × side Perimeter of square = 4 × 11 = 44 cm Circumference of circle = 2π$r$ where $r$ is the radius of the circle. The perimeter of the square = Circumference of
Question : The below bar graph shows the marks obtained by a student in an examination. What is the average mark obtained by the student?
