The product of two positive numbers is 240. If the ratio of the two numbers is 3 : 5, then what is the sum of the two numbers?
Answer & explanation
Correct answer: option 3
The ratio of the two numbers = 3 : 5
The product of two numbers = 240
Let the numbers = 3x and 5x
according to the question,
3x $\times$ 5x = 240
15x2 = 240
x2 = 16
x = 4
The sum of the two numbers = 3x + 5x = 8x = 8 $\times$ 4 = 32
