Problem number 3. Together, Mom Kangaroo and her son Jumper weigh 60 kg. Mom Kangaroo alone weighs 52 kg. How much does Jumper weigh? A. 2 kg, B. 4 kg, C. 8 kg, D. 30 kg, E. 46 kg.  The problem tells us that if we took Mom Kangaroo and Jumper and put them on a scale together, they would weigh 60 kg. We also know that Mom Kangaroo weighs 52 kg.  So what the problem is asking us is, what number plus 52 will give us 60? Or, what is 60 minus 52? We can find that that's 8.  So since 8 plus 52 makes 60, Jumper weighs 8 kg. So C. 8 kg is the correct answer.

Video Summary

Mom Kangaroo and her son Jumper together weigh 60 kg, with Mom Kangaroo alone weighing 52 kg. The problem asks for Jumper's weight. By subtracting Mom Kangaroo's weight from their combined weight (60 - 52), we find Jumper weighs 8 kg. Therefore, the correct answer is C. 8 kg.
