Answer:
1 pack of pencils. 2 pack of erasers
Step-by-step explanation:
this is a lcm based question. the reason why we use l is he asked the least set per item. so lcm of 5 and 10 is 10.that means 10 pencils are required.
10 pencils are in 1 package. so 1 pack of pencil is required. and 10 erasers means we require 2 packs of erasers to get 1 eraser per 1 pencil.
so answer is 1 pack of pencils and 2 packs of erasers
