A school bought 1,320 ties packed in 11 boxes. Each box had 10 packets and each packet had same number of ties. How many ties were there in each packet /

It is very urgent

Let the number of ties in each of the packet be xThen the number of ties in 10 packets is 10xSince 1 box contains 10 packets.So the number of ties in 11 boxes will be   11×10x=110xThe total number of ties bought by School were 1320.So it implies that,    110x=1320          x=1320110          x=12So each packet contains 12 ties.
