Ms Henderson has two jars of sweets. The jars contain the same number of sweets in total. 25% of the sweets in Jar A are mint. Two fifths of the sweets in Jar B are mint. There are 10 mint sweets in Jar A, how many mint sweets are there in Jar B?
For this question we should be familiar with percentages and their equivalents in fraction. Since they have the same number of sweets, we calculate first the total number of sweets there is in the jars and we use the percentage for Jar B to calculate its mint sweets:25% = 1/4 mint sweets in jar A which implies 1/4 * total = 10 so total = 40 sweets. Then, 2/5 of the sweets in jar B is equal to 40/5 * 2 = 16 mint sweets in jar B.
