Shubhra

Solve the following questions and find the value that will come in place of ‘?’.

  1. (0.2)^48 ÷ (0.04)^16 * (0.008)^2 = (0.2)?

    21
    22
    23
    24
    25
    Option B
    (0.2)^48 ÷ (0.04)^16 * (0.008)^2 = (0.2)?

    (0.2)^48 /(0.2)^32 * (0.2)^3 * 2 = (0.2)?

    (0.2)^48 – 32 + 6 = (0.2)?

    ? = 22

     

  2. 80 % of 605 – 14.285 % of 420 + √1444 * √16 = ? * √576

    18
    19
    20
    21
    24
    Option E
    80 % of 605 – 14.285 % of 420 + √1444 * √16 = ? * √576

    484 – 60 + 152 = ? * 24

    24 = ?

     

  3. 52 * 8 – 90 % of 40 = ? + 18 * √841

    -123
    -124
    -125
    -146
    -142
    Option E
    52 * 8 – 90 % of 40 = ? + 18 * √841

    416 – 36 = ? + 522

    ? = -142

     

  4. 120% of 700 + 60% of 385 – ? = 37 * 19

    142
    236
    328
    368
    354
    Option D

    120% of700 + 60% of 385 – ? = 37 * 19

    840 + 231 – ? = 703

    ? = 368

     

  5. 12.5% of 560 + 83.33% of 138 + 62.5% of 552 = ?

    458
    530
    450
    440
    238
    Option B
    12.5% of 560 + 83.33% of 138 + 62.5% of 552 = ?

    1/8 * 560 + 5/6 * 138 + 5/8 * 552 = ?

    70 + 115 + 345 = ?

    530 = ?

     

  6. 13^2 + 15^2 + 11^2 =?
    234
    125
    656
    515
    575
    Option D
    ?= 169 + 225 + 121 =515

     

  7. Simplify :43 * 37 + 54 * 46 =?

    4055
    4085
    4015
    4075
    4065
    Option D
    ?= (40 + 3)(40 – 3) + (50 + 4)(50 – 4)

    = 1600 – 9 + 2500 – 16

    = 4075

     

  8. Simplify:2.25 * 16 + 5.25 * 8 =? + 83
    -5
    -15
    -25
    -35
    -10
    Option A
    ? + 75 = 36 + 42 = 78

    => ? = 78 – 83 = -5

     

  9. 15% of 1080 + 25% of? = 182
    85
    80
    70
    82
    60
    Option B
    162 + 25% of ? = 182

    => 25% of ? = 182 – 162 = 20

    => ? = 20 * 100/25 = 80

     

  10. 144 * 36 – 100 * ? = -1000
    61.84
    66.84
    65.84
    65
    61
    Option A
    144 * 36 – 100 *? =-1000

    => 100 x ? = 144*36 + 1000

    = 5184 + 1000 = 6184

    => ? = 61.84
