Explanation

Pattern: Each letter is replaced by its position in the alphabet, then joined.

A=1, B=2, C=3, D=4, G=7, O=15, T=20

Check:  

CAT → C=3, A=1, T=20 → 3120 ✓  

DOG → D=4, O=15, G=7 → 4157 ✓  

So BAT:

B=2, A=1, T=20 → 2120

Explanation

Max marks each subject = 100, so total max = 100 + 100 + 100 = 300

Marks scored = 60% of 100 + 70% of 100 + 80% of 100  

= 60 + 70 + 80 = 210

Overall percentage = 210/300 × 100 = 70%

Explanation

Average speed ≠ average of speeds when distances are equal.  

Use: Average speed = Total distance / Total time

Total distance = 60 + 60 = 120 km

Time for 1st part = 60 km / 60 km/h = 1 hour  

Time for 2nd part = 60 km / 120 km/h = 0.5 hour  

Total time = 1 + 0.5 = 1.5 hours

Average speed = 120 / 1.5 = 80 km/h.

Explanation

6-2=4, 12-6=6, 20-12=8, 30-20=10  

Differences go 4, 6, 8, 10... next is 12  

So 30 + 12 = 42

Explanation

Average is equal to sum of all numbers and divided by Total numbers

= 9+18+27+36+45 = 135/5

Explanation

The three interior angles of every triangle always add up to 180 degrees

Basic Geometry Formulas

Triangle

• Area = ½ × Base × Height
• Perimeter = a + b + c
• Sum of angles = 180°

Rectangle

• Area = Length × Width
• Perimeter = 2(Length + Width)

Square

• Area = Side²
• Perimeter = 4 × Side

Circle

• Area = πr²
• Circumference = 2πr

Triangle angle

• Interior angles = 180°

Explanation

The pattern of the sequence appears to be formed by adding consecutive increments:

1 + 4 = 5

5 + 9 = 14

14 + 16 = 30

30 + 25 = 55

55 + 36 = 91

The next term in the sequence would be 91.
