Explanation

The relationship between 4 and 20 is that 20 is 5 times 4.

Similarly, to find the number that corresponds to 5 in the same way, multiply 5 by 6:

4×5=20

5×6=30

Thus, 5 is to 30 in the same way that 4 is to 20.

Explanation

To find the missing term in the sequence, let's examine the pattern:

1/3, 1/8, ?, 2/3

First, notice the denominators: 3, 8, ?, 3.

The denominators don't seem to follow a straightforward arithmetic or geometric progression. Let's look at the numerators:

1, 1, ?, 2

The numerators seem to increase by 1 each time.

If we consider that the numerators increase by 1 and the denominators are not following a clear pattern, we could assume a pattern where the numerators increase by 1 every two terms.

Following this pattern, the missing term should have a numerator of 1, and since it's the second term after 1/8, the denominator should be 5 (since 3 + 2 = 5).

So, the missing term is 1/5.

Therefore, the completed series is:

1/3, 1/8, 1/5, 2/3

Explanation

Let the Cost price of the Chair is X.

SP = X - 25% of X

720 = 0.75X

X = 960

CP = Rs. 960

So, To gain 25%, SP would be

= 960 + 25% of 960 =Rs. 1200

Explanation

HCM of 120 is not 74.

There, B is the correct option

HCF: Highest Common factor

Explanation

We'll look at the differences between terms:

5 − 2 = 3

10 − 5 = 5

17 − 10 = 7

26 − 17 = 9

So the differences are: 3, 5, 7, 9 → increasing by 2 each time (an arithmetic sequence).

The next difference should be: 11

Now add 11 to the last term:

26 + 11 = 37

Explanation

The pattern in the series appears to be a decrease of 1, then an increase of 3, repeating:

7 -> 6 (decrease by 1)

6 -> 5 (decrease by 1)

5 -> 9 (increase by 3)

9 -> 3 (decrease by 6, but pattern suggests decrease by 1)

3 -> 12 (increase by 3)

12 -> 1 (decrease by 11, but pattern suggests decrease by 1)

1 -> 15 (increase by 3)

15 -> -1 (decrease by 1)

Therefore, the next number in the series is -1.
