If the point (K, 2)is equidistant from the point (5, –2) and (1, –2) then value of K2 + 7 will be

Detailed Solution for National Level Solved Paper (MAT) - 2016 - Question 3

Using distance formula

(k – 5)2 + (4)2 = (k – 1)2 + (4)2

⇒ (k – 5)2 – (k – 1)2 = 0

⇒ (k – 5)2 = (k –1 )2

⇒ k – 5 = |k–1|

⇒ k = 5 = –k + 1

∴ 2k = 6

⇒ k = ± 3

⇒ k2 + 7 = (± 3)2 + 7 = 16

If the sum of the digits of a two digit number is 9 and the difference between the number and that formed by reversing the digits is 45 then number is
Detailed Solution for National Level Solved Paper (MAT) - 2016 - Question 7

From given question

x + y = 9    ...(i )

(10x + y) – (10y + x) = 45

9 (x – y) = 45

x – y = 5     ...(ii )

Solving equations (i ) and (ii ), we get

∴  x = 7, y = 2

So the number

= 10x + y

= 10 x 7 + 2

= 72

∴ 72 is the number
