    2. 5(n -2)
    3. (16n+24)/8
    4. (6n+12)/3

    সঠিক উত্তর: (16n+24)/8

    ব্যাখ্যা: সমাধান সঠিক উত্তর: Option C

    1. 40
    2. 41//81
    3. 82
    4. none

    সঠিক উত্তর: 41//81

    ব্যাখ্যা: সমাধান সঠিক উত্তর: Option B

  7. the product of two consecutive negative even integers is what is the larger number?

    1. -4
    2. -6
    3. 4
    4. 6

    সঠিক উত্তর: -6

    ব্যাখ্যা: সমাধান সঠিক উত্তর: Option B The product of two (two numbers multiplied together) consecutive (the numbers are right after each other in a given sequence ie- 1,2 in the sequence 12,3,4 or 20,30 in 10,20,30) negative ( the numbers must be from the scale below zero ie “-3” is a negative number- which happens to be the temperature here today) even integers (the numbers are multiples of 2 ie from this sequence .(..-8,-6,-4,-2,0,2,4,6,8....) is 24. And, (-6) x (-4) = 24

  8. how many odd, positive divisors does 540 have?

    1. 6
    2. 8
    3. 12
    4. 15

    সঠিক উত্তর: 8

    ব্যাখ্যা: সমাধান সঠিক উত্তর: Option B

  9. if A, B, C and D are positive integers such that 4A = 9B, 17C = 11D, and 5C = 12A, then the arrangement of the four numbers from greatest to least is -

    1. CDAB
    2. BACD
    3. DCAB
    4. DCBA

    সঠিক উত্তর: DCAB

    ব্যাখ্যা: সমাধান সঠিক উত্তর: Option C 4A = 9B => B = 4/9 A 5C = 12A => C = 12/5 A 17C = 11D => D = 17/11 C = 17/11 (12/5 A) = 204/55 A So the order from greatest to least is, 204/55 A, 12/5 A, A, 4/9 A Nothing but, DCAB

  10. the average (arithmetic mean) of 4 different integers is . if the largest integer is 90, what is the least possible value of the smallest integer?

    1. 1
    2. 19
    3. 29
    4. 33

    সঠিক উত্তর: 33

    ব্যাখ্যা: সমাধান সঠিক উত্তর: Option D the sum of the four different numbers is 75 * 4 = 300, the largest one is 90, so the sum of the rest three numbers is 300-90 = 210, the average of them is 210/3 = 70. Since the 4 numbers are different, the second largest and third largest should be 89,88. Hence, the least number is 70- ( (89-70) + (88 - 70 )) = 70 - 37 = 33.
