Answer: 5 boxes of ladoos, 6 boxes of samosas
Step-by-step explanation: To calculate this answer, we can find the LCM (least common multiple) of 20 and 24. The LCM is the smallest number can be divided evenly (no fractions, decimals, etc.) by any two given numbers. In this case, the LCM of 20 and 24 is 120. In the context of this problem, this means that we will have 120 ladoos and 120 samosas, which is a 1:1 ratio as specified by the problem. Then, we can divide the LCM by each of our factors to find how many boxes of each there will be (120/24=5, 120/20=6).
