Explanation

Cost Price = Rs. 8000

Gain = 25%

Selling Price = 8000 + (25% of 8000)

= 8000 + (0.25 × 8000)

= 8000 + 2000

= 10000

Given:

3x + y = 10 ...(i)

x - 4y = -1 ...(ii)

From (ii):

x = -1 + 4y ...(iii)

Put (iii) in (i):

3(-1 + 4y) + y = 10

-3 + 12y + y = 10

13y = 13

y = 1

Explanation

Given:

- Average age of 5 members = 21  

  → Total age of 5 members = 21 × 5 = 105

- When grandfather is included (6 members), average becomes 21 + 9 = 30  

  → Total age of 6 members = 30 × 6 = 180

Now, Grandfather's age = 180 – 105 = 75 years

Explanation

The husband and wife: 2

Six married sons: 6

Six daughters-in-law (wives of the sons): 6

30 grandchildren (6 sons x 5 children each): 30

Total family members: 2 + 6 + 6 + 30 = 44

The correct answer is 44.

Explanation

Step 1: Find the pattern (differences)

6 − 2 = 4

12 − 6 = 6

20 − 12 = 8

30 − 20 = 10

42 − 30 = 12

The differences increase by 2 each time:

4, 6, 8, 10, 12, 14

Step 2: Find the next term

Next number = 42 + 14 = 56

Explanation

Given sequence: 4, 11, 7, 14, 10, 17, __, 20

Two alternating series are used:

First series: 4 → 7 → 10 → 13 (+3 each time)

Second series: 11 → 14 → 17 → 20 (+3 each time)

Missing number: 13

Explanation

Let's say B's income is 100%.

Then, A's income is 60% (since it's 40% less than B's).

To find out how much percent B's income is more than A's income, we need to find the difference between their incomes and divide it by A's income, then multiply by 100:

((B's income - A's income) / A's income) * 100

= ((100 - 60) / 60) * 100

= (40 / 60) * 100

= 66.66%

So, B's income is 66.66% more than A's income.
