Statement 1: 0.4 × 0.04 × 100 = 1.6.
Statement 2: 0.4 × 0.04 × 100 = 0.4 × (0.04 × 100) = 0.4 × 4 = 1.6
Which of the following options is correct?
Both the statements are true.
Both the statements are false.
Statement 1 is true, and statement 2 is false.
Statement 1 is false, and statement 2 is true.
Answer
0.4 × 0.04 × 100 = 0.4 × (0.04 × 100) = 0.4 × 4 = 1.6
So Statement 1 is true and Statement 2 correctly shows the working and is also true.
Hence, option 1 is the correct option.
Statement 1: m and n are two numbers such that the difference between them is 17. ⇒ m - n = 17
Statement 2: If m is greater than n; m - n = 17 and if n is greater than m; n - m = 17
Which of the following options is correct?
Both the statements are true.
Both the statements are false.
Statement 1 is true, and statement 2 is false.
Statement 1 is false, and statement 2 is true.
Answer
The difference between two numbers being 17 does not necessarily mean m - n = 17, because we do not know which number is greater.
So Statement 1 is false.
Statement 2 correctly accounts for both cases (m - n = 17 when m > n and n - m = 17 when n > m), so it is true.
Hence, option 4 is the correct option.
