Explanation

Sum of the 10 numbers = 230

If each number is increased by 4, the total increase =

4 * 10 = 40

The new sum = 230 + 40 = 270 The new average = 270/10 = 27

Explanation

To find the average of:  

22, 33, 44, 55, 66

Step 1: Add the numbers  

22 + 33 + 44 + 55 + 66 = 220

Step 2: Divide by the number of values  

220 ÷ 5 = 44

Explanation

To divide 180 in the ratio 1:3:8:

Step 1: Add the parts:  

1 + 3 + 8 = 12 parts

Step 2:  

Each part = 180 ÷ 12 = 15

Now multiply each ratio by 15:  

1 × 15 = 15  

3 × 15 = 45  

8 × 15 = 120

Explanation

Total marks obtained = 75 + 85 + 90 = 250  

Total marks = 300

Percentage = (250 / 300) × 100 = 83.33%

Explanation

using BODMAS rule:

Expression:  

(2 + 4 × 3 − 5) ÷ 3

Step 1: Brackets first  

Inside brackets:  

→ 4 × 3 = 12  

→ Now: (2 + 12 − 5) ÷ 3

→ 2 + 12 = 14  

→ 14 − 5 = 9  

Now the expression becomes:  

→ 9 ÷ 3 = 3
