    145
    130
    150
    None
    Option A
    Solution:
    (256432 + 314281) / (2140+1456) = x
    570713/3596=x
    X=160.
  2. 448.62 – 229.45/(14.9% of 118) = ?
    15
    21
    13
    18
    None
    Option C
    Solution:
    448.62 – 229.45 / (14.9% of 118) = x
    450-230/(15% of 120)=x
    220/18=13.
  3. 2810.65 – 195/12.2 * 10 = ?
    2515
    2360
    2425
    2650
    None
    Option D
    Solution:
    2810.65 – 195 / 12.2 * 10 = x
    2810 – 160=x
    x=2650.
  4. (28.07 * 4.97 + 15 * 6.05) / (7.032 + √256.01 + 13.111) = ?
    5
    3
    4
    7
    None
    Option B
    Solution:
    (28*5 + 15*6) / (49+16+13)=x
    (140+90) / 78=x
    230/78=x
    x=3.
  5. [(6/1.8)*(22/0.4)]/[(56/7)*(42/10)] = ?
    9
    4
    5
    6
    None
    Option B
    Solution:
    [(6/1.8)*(22/0.4)] / [(56/7)*(42/10)]=x
    [(6/2)*(22/0.5)] / [(56/7)*(42/10)]=x
    (3*44) / (8*4.2)=x
    132/33.6 =132/34=x
    x=4.
  6. (2914.01/31.1) (1.99/3.01 * 510.01/169.99) = ?
    194
    186
    166
    175
    None
    Option A
    Solution:
    (2914.01/31.1) (1.99/3.01*510.01/169.99)=?
    2915/30 (2/3 * 510/170)=x
    97 *2=x
    x=194.
  7. 1787.44/34.88 * 48.79 + 1.06 = ?
    2300
    2850
    2500
    2460
    None
    Option C
    Solution:
    1787.44 34.88 * 48.79 + 1.06 = x
    1785/35 * 49 + 1= x
    51*49 + 1 = x
    x=2500.
  8. √(√44950 + √?) = 16
    1940
    1570
    1825
    1640
    None
    Option A
    Solution:
    √(√44950+ √?) = 16
    Squaring on both side
    √44950+ √x= 256
    212+ √x=256
    √x=256-212=44
    Then x= 442=1940.
  9. √4360 – √680 + 46.02 = ?
    78
    73
    92
    86
    None
