The area of a triangle with vertices (p, 2 – 2p), (1 – p, 2p) and (–4 –6, 6 – 2p) is 70 sq. units. Then, the number of possible integral values of p is 1. 0 2. 1 3. 2 4. 3

Answer»

Correct option is 2. 1

By using area of triangle formula

We get, (8p² + 4p - 4) = \(\pm{}\)140

⇒ 8p²+ 4p - 144 = 0

⇒ p = 4 or p = -9/2

Other equation 8p²+ 4p + 136 = 0 does not have real roots So, numbers of integral values = 1

Three spheres of radius 6 cm, x cam and y cm are melted to form a single sphere of radius 12 cm. If xy is equal to 80, then the value of x + y is 1. 21 2. 18 3. 24 4. 42

Answer»

2. 18

Given xy = 80 and 6³+ x³ + y³ = 123 ⇒ x³ + y³ = 1512

⇒ (x + y)³ - 3xy (x+y) = 1512

Let x + y = a

So, given equation reduces to a³ - 240a - 1512 = 0

Now, a = 18 is root of above equation ⇒ x + y = 18

3259.	A and b are roots of a quadratic equation x2 + 5x + d = 0 , while a and c are the roots of the quadratic equation x2 + 6x + 2d = 0 . If there is only one common root in the two equations, then value of d is 1. –2 2. –4 3. 2 4. 4
Answer» 4. 4 x² + 5x + d =0 a + b = -5 ab = d x² + 6x + 2d = 0 a + c = -6 ac = 2d ac = 2ab c = 2b ⇒ a + 2b = -6 a + b = -5 ⇒ b = -1 ⇒ a = -4 ∴ d = ab = (-4) (-1) = 4

3259.

A and b are roots of a quadratic equation x2 + 5x + d = 0 , while a and c are the roots of the quadratic equation x2 + 6x + 2d = 0 . If there is only one common root in the two equations, then value of d is 1. –2 2. –4 3. 2 4. 4

Answer»

4. 4

x² + 5x + d =0

a + b = -5

ab = d

x² + 6x + 2d = 0

a + c = -6

ac = 2d

ac = 2ab

c = 2b

⇒ a + 2b = -6

a + b = -5

⇒ b = -1 ⇒ a = -4

∴ d = ab = (-4) (-1) = 4

The median of certain observations 17, 18, 23, 27 x – 3, x + 5, 45, 49, 74 and 85 arranged in an ascending order is 35. Later on, it was found that one observation 72 was misread as 27 by mistake. The correct median of the data is: 1. 36 2. 38 3. 42 4. 47

Answer»

3. 42

17, 18, 23, 27, x –3, x + 5, 45, 49, 74, 85

\(\frac{x-3+x+5}{2}=35\)

\(\frac{2x+2}{2}=35\)

x + 1 = 35

x = 34

∴ The number are 17, 18, 23, 31, 39, 45, 49, 72, 74, 85

∴ Median = \(\frac{39+45}{2}=\frac{84}{2}=42\)
