Explanation

An isosceles triangle is a triangle with two sides of equal length.

If all three sides are equal, it is called an equilateral triangle.

A scalene triangle has all sides of different lengths, and a right triangle has one right angle (90 degrees).

Explanation

Let length = L

Width = L - 3

Perimeter = 2(L + W)

110 = 2(L + L - 3)

110 = 2(2L - 3)

110 = 4L - 6

4L = 116

L = 29

15 men × 10 days = M2 × 3 days

M2 = 50

More men = 50 - 15 = 35

Explanation

Cost Price = Rs. 8000

Gain = 25%

Selling Price = 8000 + (25% of 8000)

= 8000 + (0.25 × 8000)

= 8000 + 2000

= 10000

Explanation

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
