 Puzzle ID: #676 Fun: (2.17) Difficulty: (1.34) Category: Math Submitted By: vikass Corrected By: Dave

You have stealthily raided your small child's piggy bank. You feel guilty as you count the money. You have the same number of dimes and quarters, totaling exactly \$2.45. When you turn honest and put it back, how many of each coin will you need to replace? (Note that your child keeps a record of how much she puts in and in what denomination)

 Sane Feb 17, 2005 You have the same number of dimes and quarters, totaling exactly \$2.45. 10(x) + (25)x = 24 500 35x = 24500 x = 700 (/100) Nice teaser. phrebh Jun 27, 2005 Why don't you just look at your child's record of it and give the math a skip?

Jimbo Apr 10, 2007 What's a dime? javaguru Jan 29, 2009 How does 245/35 = 7 become a teaser? Are there no standards? And how does 245/35 get rated 2.15 on the fun scale and well over 1 on the difficulty scale?
