Answer:
10%
Step-by-step explanation:
Let the third number is X.
then first number = (100-30)% of X
= 70% of X = 7X/10
Second number is (63X/100)
Difference = 7X/10 - 63X/100 = 7X/10
So required percentage is, difference is what percent of first number
=> (7X/100 * 10/7X * 100 )% = 10%
23 + 12x <= 75
12x <= 52
if you want an integer, answer is 4 hours
if fractions of an hour are allowed than the answer is 4 and 1 / 3 or 13 / 3
