If 382 is written as 238, 473 as 347 and so on, then which of the following two numbers will have least difference between them?

A) 473 & 382 B) 629 & 728
C) 629 & 847 D) 728 & 847

Explanation:

The given numbers are :

382  473  568  728  847  629

When changes are made as given in the question, numbers become as follows :

238  347  856  872  784  962

Again now, find out the difference between the numbers given in options as given below:

(1) 473 - 382  => 347 - 238 = 109

(2) 629 - 728  => 962 - 872 = 90

(3) 629 - 847  => 962 - 784 = 178

(4) 728 - 847  => 872 - 784 = 88

Q:

Two dice are thrown simultaneously. What is the probability of getting two numbers whose product is even?

A) 3/4 B) 3/8
C) 5/16 D) 2/7
 
Answer & Explanation Answer: A) 3/4

Explanation:

In a simultaneous throw of two dice, we have n(S) = (6 x 6) = 36.

Then, E= {(1, 2), (1, 4), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 2), (3,4),(3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 2), (5, 4), (5, 6), (6, 1),6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

n(E) = 27.

P(E) = n(E)/n(S) = 27/36 = 3/4.

A) Only argument I is strong B) Only argument II is strong
C) Neither I nor II is strong D) Both I and II are strong
