Answers :
1) Answer: E
30% of 170 + 25% of 120 =? * 9
51 + 30 = ? * 9
? = 9
2) Answer: B
? * 29 = 117 * √169 + 51.5 * 2
? * 29 = 1521 + 103
? = 56
3) Answer: C
(0.5)12 * (0.0625)10 ÷ (0.25)8 = (0.5)?
(0.5)12 * (0.5)40 ÷ (0.5)16 = (0.5)?
(0.5)12 + (40 – 16) = (0.5)?
(0.5)36 = (0.5)?
? = 36
4) Answer: A
80% of 875 – 200 = ? + 25 % of 1740
700 – 200 = ? + 435
? = 65
5) Answer: C
48 * 25 – 35 * 25 = ?2 + 1
1200 – 875 = ?2 + 1
? = 18
6) Answer: C
From I =>5x2 – 26x + 33 = 0
5x2 – 11x -15x + 33 = 0
x(5x-11)-3(5x-11) = 0
=> (5x – 11) (x – 3) = 0
=> x = 2.2, 3
From II =>2y2 – 15y + 27 = 0
2y2 – 9y – 6y +27 = 0
y(2y-9)-3(2y-9) = 0
=> (y – 3) (2y – 9) = 0
=> y = 3, 4.5
Hence, x ≤ y
7) Answer: E
From I =>3x2 – 8x + 4 = 0
3x2 – 6x – 2x + 4 = 0
3x(x-2) -2(x-2) = 0
=>(x – 2) (3x – 2) = 0
=> x = 2, 2/3
From II =>5y2 – 18y + 16 = 0
5y2 – 10y -8y + 16 = 0
5y(y-2)-8(y-2) =0
=> (5y – 8) (y – 2) = 0
=> y = 2, 8/5
Hence, relationship between x and y cannot be determined
8) Answer: B
From I =>x2 – 13x + 42 = 0
x2 – 7x -6x + 42 = 0
x(x-7)-6(x-7) = 0
=> (x – 7) (x – 6) = 0
=> x = 6, 7
From II =>y2 – 9y + 20 = 0
y2 – 5y -4y + 20 = 0
y(y-5)-4(y-5) = 0
=> (y – 5) (y – 4) = 0
=> y = 4, 5
Hence, x > y
9) Answer: B
From I =>3x2 – 23x + 40 = 0
3x2 – 15x -8x + 40 = 0
3x(x-5)-8(x-5) = 0
=> (3x – 8) (x – 5) = 0
=> x = 8/3, 5
From II =>6y2 + y – 2 = 0
6y2 + 4y -3y – 2 = 0
2y(3y+2)-1(3y+2) = 0
=> (2y – 1) (3y + 2) = 0
=> y = 1/2, -2/3
Hence, x > y
10) Answer: A
From I =>3x2 + 14x + 8 = 0
3x2 + 12x +2x + 8 = 0
3x(x+4)+2(x+4) = 0
=> (3x + 2) (x + 4) = 0
=> x = -2/3, -4
From II =>2y2 – 17y + 36 = 0
2y2 – 9y -8y + 36 = 0
y(2y-9)-4(2y-9) = 0
=> (2y – 9) (y – 4) = 0
=> y = 9/2, 4
Hence, x < y
