Ohh. So is it 25? Since 25% of 40 is 10, added to equal 50?What is 10% greater than 40?
What is 30% greater than 40?
What is 15% greater than 40?
I will show you how to do the last one I listed.
15% of 40 is 6. So 15% greater than 40 would be 40+6 or 46.
Can you now try to solve your problem?
When Subhotosh Kahn asked "What is the base?" he did not mean base of the numeration system. He was referring to the base of the percentage. Any time you talk about a percentage you have to think "percent of WHAT?" This problem asks you to find a number, p, such that "50 is p percent greater than 40". When Subhotosh Kahn asked "What is the base?" he wanted you to think "p percent of what?"Base 10? I'm kinda confused, this is the exact wording as it was on my test but I don't know the answer.
50 is p% greater than 40. p = ?
