Question

find the numbers in the ratio 2 is to 3 is to 5the sum of whose squares is 608

Answer 1

Step-by-step explanation:

• Let the no. be 2 x , 3 x and 5 x.

A/Q, (2 x )² + (3 x )² + (5 x )² = 608

⇒ 4 x ² + 9 x² + 25 x² = 608

⇒ 38 x ² = 608

⇒ x² = 16

∴ x = 4.

• So the no. are :
• 2 x = 8
• 3 x = 12
• 5 x = 20.
