**Question-1)**

**Average of five numbers is 20. If each number is multiplied by 2, what will be the new average?**

**Answer & Solutions**

The new average = Initial average × 2

= 20 × 2 = 40

**Question-2)**

**If the average of three consecutive even numbers is 34, find the largest of these numbers.**

**Answer & Solutions**

Let the first number is X, then the next two even numbers would be X+2, X+4

As per question;

${X+X+2+X+4}/3$ = 34

${3X+6}/3$ = 34

3X + 6 = 102

3X = 96

X = 32

Largest number would be = 32 + 4 = 36

**Question-3)**

**If the average of three consecutive even numbers is 34, find the largest of these numbers.**

**Answer & Solutions**

By Using formula

Average = ${\text"Sum of the Quantity"}/{ \text"Number of Quantity"}$

Sum of first five natural numbers =1+2+3+4+5 = 15

Number of quantities= 5

On putting these values in the formula: Average = $15/5$ = 3

**Question-4)**

**If the sum is 240 and average is 40, find the number of quantities.**

**Answer & Solutions**

By Using formula

Average = ${\text"Sum of the Quantity"}/{ \text"Number of Quantity"}$

So, Number of Quantities =$240/40$ =6
