Q-(1) Sol-(2)
Q-(2) Sol-(1)
x=7.5,1.33
y=4.5,4.5
Q-(3) Sol-(1)
(I) x2=3481
x= + 59
(II) 3y2=60
y2=20
So, relationship can not be set up.
Q-(4) Sol-(4)
(I) x = +16
(II) y = 16
x < y
Q-(5) Sol-(3)
x=0.799,0.714
y=0.875,0.857
x < y
Q-(6) Sol-(1)
Q-(7) Sol-(1)
Q-(8) Sol-(4)
Let the age of Manish and Suresh is 5x and 6x year.
42x + 56 = 40x + 64
x = 4
Required Difference = 6 × 4 – 5 × 4
= 4 year
Q-(9) Sol-(4)
