1. The result of subtraction of two numbers is equal to 3/7 of their sum. If the smaller number is 6, what is the other number?
- A. 9
- B. 9
- C. 9
- D. 9
Answer: Option B
Explanation:
Let the greater number is = x
and the smaller number is = y
According to the question,
x - y = 3/7 (x + y)
or, 7x - 7y = 3x + 3y
or, 7x - 3y = 3y + 7y
or, 4x = 10y
or, 4x = 10*6 [As the smaller number is 6]
or, 4x = 60
or, x = 15
Ans: The greater number is 15
