The sum of two numbers is 24 and their product is 143. Therefore, the sum of the reciprocal of the two number is

  1. 119/24

  2. 24/143

  3. 143/24

  4. 24/119

  5. None of these


Correct Option: B
Explanation:

Let the first number is x and second number is y. then, x + y = 24 --------- (1) x y = 143 ---------- (2) On dividing (1) by (2): 1/x + 1/y = 24 / 143

The monthly income of three persons A, B and C are in the ratio 2 : 5 : 4. If their total income is K, then the sum of income of B and C is

  1. 9K/11

  2. 7K/11

  3. 6K/11

  4. 5K/11

  5. None of these


Correct Option: A
Explanation:

Let the income of A is 2 x, B is 5 x and C is 4 x Now,11 x = K (Given) x = K /11 Therefore, B's income = 5K/11 and C's income = 4K/11 Therefore, (B + C)'s total income = 9K/11

A and B can complete a piece of work together in 30/11 days. A alone can do the work in 6 days, B alone can do the same work in

  1. 1/6 days

  2. 1/5 days

  3. 5 days

  4. 6 days

  5. None of these


Correct Option: C
Explanation:

(A + B)'s 1 day work = 11/30 A's 1 day work = 1/6 Therefore, B's 1 day work = 11/30 - 1/6 = 6/30 = 1/5 Therefore, B alone can do the same work in = 5 days

Rs. 1200 is to be divided between three people. If the first one gets 1/4, the second one get 1/8 and the third gets the rest. Then the difference between the highest and lowest amount received is

  1. Rs. 600

  2. Rs. 750

  3. Rs. 150

  4. Rs. 300

  5. None of these


Correct Option: A
Explanation:

1/4 of Rs. 1200 = Rs. 300 --------- (First one gets) 1/8 of Rs. 1200 = Rs. 150 --------- (Amount received by second person) Therefore, amount received by the third one = Rs. (1200 - 450) = Rs. 750 Therefore, required difference = Rs. (750 - 150) = Rs. 600

A and B can do a piece of work in 4 days and 6 days respectively. What is the number of days required to complete the work when both work together?

  1. 2.3

  2. 2.1

  3. 10/24

  4. 2.4

  5. None of these


Correct Option: D
