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?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 32
Let two number be 3x and 5x
We need to find the sum of two numbers when product is 240
According to question,
3x x 5x = 240
⇒ 15x2 = 240
⇒ x2 = 240/15 = 16
x = 4
Sum = 3x + 5x = 8x
⇒ 8 x 4 = 32
