Answer 2

Answer:

Total amount is $ 450

Explanation:

Let,

Ratio of sharing :

• 3x
• 5x
• 7x

The smallest share = $ 90

So,

The smallest share in ratio = 3x

⇒ 3x = $ 90

⇒ 3x = 90

⇒ x = 90 / 3

⇒ x = 30

______________________

★ Value of 5x :

⇒ 5 (30)

⇒ 5 × 30

⇒ 150

______________________

★ Value of 7x :

⇒ 7 (30)

⇒ 7 × 30

⇒ 210

______________________

Hence,

★ 3x = $ 90

★ 5x = $ 150

★ 7x = $ 210

______________________

Therefore,

Total amount :

⇒ $ 90 + $ 150 + $ 210

⇒ $ 450

Total amount is $ 450
