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
