Equation of the line through the points (7, 5)
and (2, 9) is given by
y−5
x−7
=
9−5

⇒ 4x + 5y − 53 = 0
Equation of the line parallel to 4x + 5y − 53 = 0 is
4x + 5y + k = 0
It passes through (3, −4) we have 12 − 20 + k = 0
∵k=8
Thus the required line is 4x + 5y + 8 = 0

Ans: (d)
Explanation:
(a, a), (b, b), (c, c) ℇ R
So R is a reflexive relation
But (𝑎, 𝑏)ℇ R and (b, a) ∉ R
Thus, R is not a symmetric relation.
Also, (a, b), (b, c) ℇ R ⇒ (a, c) ∉ R
Hence R is not a transitive relation

Explanation :
Since the cost curve is linear we consider cost curve as y=Ax+B where y is total
cost. Now for x=80, y=2,20,000. ∴ 2,20,000 = 80A+B…….(i)
and for x = 125; y=2,87,500 ∴ 2,87,500 = 125A+B………(ii)
Subtracting (i) from (ii) 45A=67,500 or A=1500
From (i) 2,20,000 – 1500 (80) = B or B =2,20,000-1,20,000=1,00,000
Thus equation of cost line is y = 1,500x+1,00,000.
For x=95, y=1,42,500+1,00,000=Rs. 2,42,500.
∴ Cost of 95 T.V. set will be Rs. 2,42,500.

Explanation : Average age of 10 students = 20 yrs
The sum of age of 10 students = 20 x 10 = 200 yrs
If two boys are increased
The total no of students = 10+2=12
And average increased by 4 yrs
Then new average = 20 + 4 = 24
The sum of age of 12 student = 24 x 12 = 288
The sum of age of two boys = 288 – 200 = 88

Average age of two boys = 2 = 44
