1/5 of a number is equal to 5/8 of the second number. If 35 is added to the first number then it becomes 4 times of second number. What is the second number?
Correct Answer: 40
Explanation:
Let first and second numbers are p & q.
p/5 = 5q/8
∴ p/q = 25/8 ...(i)
p + 35 = 4q
or 25q/8 + 35= 4q
∴ q = 40.
