1. If 25% of a number is subtracted from a second number, the second number reduces to its five-sixth .What is the ratio of the first number to the second number ?
- A. 1:3
- B. 1:3
- C. 1:3
- D. 1:3
Answer: Option B
Explanation:
A = First Number
B = Second Number
B - 1/4A = 5/6B
B = 1/4A + 5/6B
1/6B = 1/4A
4B = 6A
2B = 3A
2/3B = A
A:B = 2:3
