This phrase will invoke fear into the minds of any Primary 6 (A 12 year old) who has ever attempted this dangerous question because of how ridiculously difficult it is (MOE pls don't sue me) Here's the question: Helen and Ivan had the same number of coins. Helen had a number of 50-cent coins and 64 20-cent coins. These coins had a mass of 1.134 kg. Ivan had a number of 50-cent coins and 104 20-cent coins. Question 1: Who has more money in coins and by how much? Question 2: Given that each 20-cent coin is 2.7 g heavier than 50 cent coin, what’s the mass of Ivan’s coins in kg (kilograms)?
