Q1-(5)
X = -1.7,- 5
Y = 2,- 3

Q2-(1)
X = -13,-19
Y = -21,-23

Q3-(4)
X = 2.2,3.8
Y = 3.8,4

Q4-(1)
X = -6, -2.2
Y = -7,-9

Q5-(1)
X = 19
Y = 18.9,-18.9

Q6-(1)
Let the initial amount of milk in the jar be K.
Then, 972 =
or,
K = 4096 milliliters = 4.096 litres

Q7-(4)
Let the present age of B be Q years
Then C = 30 + Q
Again, A + C = Q + 30
or, A = Q + 30 - Q - 8 = 22 years

Q8-(3)
S.P. of 65% goods = 0.65x × 0.98 = 0.637x
S.P. of 65% goods = 0.35x × 0.16 = 0.406x
Total S.P. = 0.637x + 0.406x = 1.043x
.˙. Profit = 0.043x
Now, 0.043x = 1290
x =1290 / 0.043 = 30000

Q9-(4)
P = 512
64 (First year)
64 + 8 (Second)
64 + 16 + 1(third year)

A (  3   :    5 )      = 8  (  × 3 × 2  )
B  ( 1 : 5 )          = 6  (  × 4 × 3 )
A = 18 : 30
B = 12 : 60
Required ratio
