9) Answer: b)
10) Answer:Â d)
(x+y)/z = 6/5Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â (y + z)/x = 9/2
x + y = 6Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â x = 2
2 + y = 6Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â y = 4
z = 5
x + z/y = 2 + (5/4) = 13/4

12) Answer: c)
3x+ 5y + 7z = 56 —— (1)
9x+8y +21z =126 —– (2)
Multiplying eq. (i) × 3
9x + 15y + 21z = 168
Subtracting eq. from (i)
9x + 15y + 21z = 168
(-)9x+8y +21z =126
________________________
7y = 42
y = 6
13) Answer: b)
4M + 6 O + 9 G = 305          – (i)
3 M + 4 O + 2 G = 145          – (ii)
Hence, Eq (i) × 2 – Eq. (ii)
5 M + 8.0 + 16 G = (305 × 2 – 145) = 465
14) Answer: c)
