Question

the product of three numbers is 100. If two of the numbers are 10 and 2 , what is the third

Answer 1

Given:-

• The product of three numbers is 100.

• Two of the numbers are 10 and 2.

To Find:-

• Find the third number.

Concept:-

• Firstly, let's understand the concept.We should form an equation according to the condition by taking the unknown number and substitute the given values in it and equate it.

Solution:-

Let the third number be x.

First number = 10

Second number = 2

According to the question we have!

⟹ 10 × 2 × x = 100

⟹ 20 × x = 100

⟹ 20x = 100

⟹ x = 100/20

⟹ x = 5

Therefore,

The third number is 5.

Verification:-

⟹ 10 × 2 × x = 100

⟹ x = 5

⟹ 10 × 2 × 5 = 100

⟹ 20 × 5 = 100

⟹ 100 = 100

⟹ LHS = RHS

Hence,

It is verified.

Answer 2

Answer:

so the right answer is 5.

let third no. be x

first no. 10

second no. 2

10*2*x=100

20*x=100

x=100/20

x=5

to check the answer

2*10*5=100
