Answer Key-
- Sol-(3)
2x(x-3) -5(x-3) = 0
x = 3,2.5
(II) 2y2 - 8y - 7y + 28= 0
2y(y-4) -7(y-4) = 0
y = 4,3.5
x < y

3. Sol-(1)
4. Sol-(4)
5. Sol-(5)
Relation can't be established.
6 Sol-(3)
Let the income of A and B be Rs. 5x and Rs.4x respectively and let their expenditures be Rs. 3y and Rs. 2y respectively.
Then, 5x - 3y = 1600 .. (i) and 4x-2y = 1600
on multiplying (i) by 2, (ii) by 3 and subtracting . We get : 2x = 1600
x = 800
A's income = Rs. 5x = Rs. (5 × 800)
= Rs. 4000
