This year’s Arbor Day, the Experimental Primary School received a batch of saplings. If there are 15 trees in each bundle, it will be just right, if there are 10 trees in each bundle, it will be just right, and if there are 20 trees in each bundle, how many saplings will there be at least?
今年植树节，实验小学领了一批树苗，如果每捆15棵，正好分光，如果每捆10棵也正好分光，如果每捆20棵同样正好分光，六年级领的树苗至少有多少棵？
