Explanation

Look at the pattern:

1 + 2 = 5  

1 square + 2 square = 1 + 4 = 5

2 + 3 = 13  

2 square + 3 square = 4 + 9 = 13

3 + 4 = 25  

3 square + 4 square = 9 + 16 = 25

So the rule is: a + b = a square + b square

Now find 4 + 5  

4 square + 5 square = 16 + 25 = 41

Solution

Cost Price (CP) = Rs. 800

Selling Price (SP) = Rs. 720

Loss = CP − SP

= 800 − 720 = Rs. 80

Loss % = (Loss ÷ CP) × 100

= (80 ÷ 800) × 100

= 10%

Explanation

The sequence is arranged in groups where the numbers increase by 2:

• 3, 5, 7
• 10, 12, 14
• 24, 26, 28

So after 24, 26, the next number is:

26 + 2 = 28

Explanation

• The series alternates between subtracting 1 and adding 2:
  • 12 → 11 (subtract 1)
  • 11 → 13 (add 2)
  • 13 → 12 (subtract 1)
  • 12 → 14 (add 2)
  • 14 → 13 (subtract 1)

Following this alternating pattern, the next step should be adding 2 to 13:

$$13 + 2 = 15$$
