Answer 2

Answer:

Explanation:

Given :

• HCF of two numbers is 2.
• LCM of two numbers is 70.

To Find :

• The number.

Formula to be used :

• LCM × HCF = Product of two numbers

Solution :

Let, first number be "P". and second number be "2P".

★ Numbers,

LCM × HCF = Product of two numbers

⇒70 × 2 = P × 2P

⇒ 140 = 2P²

⇒ P² = 70

⇒ P = 8.36

Hence,

• First number = P = 8.36
• Second number = 2P = 2 × 8.3 = 16.72

★ Verification,

LCM × HCF = Product of two numbers

⇒ 70 × 2 = 8.36 × 16.72

⇒ 140 = 139.7792 ≈ 140

⇒ 140 = 140

Hence, Verified!!
