Explanation:

When positive integer m is divided by positive integer n, the remainder is 6. If m/n = 112.15 what is the value of n? Correct Answer 40 Here, divident is m, divisor is n, quotient is 112 and remainder is 6. Again, m/n = 112.15  or,  m = 112.15n Now,   divident = divisor x quotient + remainder or,   m = n x 112 + 6 or,  112.15n = 112n + 6 or,   112.15n - 112n = 6 or,   0.15n = 6 or,   n = 40

Explanation:

If the sum of five consecutive positive integers is A, then the sum of the next five consecutive integers in terms of A is : Correct Answer A + 25 The sum of five consecutive positive integers is A, next 5 consecutive will gain additional 5*5 = 25,  so the sum of the next five consecutive integers in terms of A is = A + 25 ans: A + 25

Explanation:

The average income of 10 BBA graduates is Tk. x. The individual income of 5 MBA graduates is Tk. 100y each. What is the average income of these 15 graduates? Correct Answer (10x+500y)/15 Total income of BBA graduates = 10x Total income of MBA graduates = 5 x 100y = 500y Average income of all of the graduates = (10x + 500y) / (10 + 5)                                                                 = (10x + 500y) / 15

Explanation:

If d= c-b/a-b, then b =? Correct Answer adc-1/d-1 D = c-b/a-bor, ad-bd = c-bor, b-bd = c-ador, b(1-d) = c-ador, b= (c-ad)/(1-d)

Explanation:

Tk. 1000 is divided among A, B and C so that A has twice as much as B and B has thrice as much as C. How much did B receive? Correct Answer 300 Here,   A : B = 2 : 1 = (2 x 3) : (1 x 3) = 6 : 3 And,  B : C = 3 : 1 So,   A : B : C = 6 : 3 : 1 B received = 3 / (6 + 3 + 1) x 1000 = 300 TK.

Explanation:

A room contains 200 people, 25% of whom are graduates. A group of people, 30% of whom are graduates, leave the room. Of the remaining people, 10% are graduates. How many people did leave the room? Correct Answer 150 Let the number of people leaving be L. Remaining people = 200 -  L Total graduates = 25% of 200 = 50 Leaving graduates = 30% of L  = 0.3L Remaining graduates = 50 - 0.3L ATQ,  10% of (200 -  L) = 50 - 0.3L or,  20 - 0.1L  = 50 - 0.3L or,  0.3L - 0.1L = 50 - 20 or,  0.2L = 30 or,  L = 30 / 0.2 = 150

Explanation:

Explanation:

If n is an even integer which of the following must be an odd integer? Correct Answer 3(n+1) If n is an even integer then n + 1 must be an odd integer. Product of two odd integers is always an odd number. So, 3(n + 1) must be an odd number.

Explanation:

If (x+3y)=15 and x=-1.5y, then x=? Correct Answer -15 Here. x = - 1.5y or,  x = - 3y/2 or,  y = - 2x/3 Now,  x + 3y = 15 or,   x + 3( - 2x/3) = 15 or,  x - 2x = 15 or,  - x = 15 SO,  x = - 15

Explanation:

How much salt must we add to 10 grams of a 20% salt solution to strengthen it into a 50% solution? Correct Answer 6 gm Let the amount need to be added be x grams. So,  x + 20% of 10 = 50% of (10 + x) or,  x + 2 = 5 + 0.5x or,  x - 0.5x = 5 - 2 or,  0.5x = 3 So,   x = 6 grams
