AND finally she used 105 M. She is left with 27 M
ribbon what length of ribbor did she buy?​

Answer 1

Answer:

160m

Explanation:

let she buy x m

first use x/5

remaining= x-x/5=4x/5

now use 1/8 i.e  4x/5*1/8=x/10

remaining=4x/5-x/10=7x/10

finally used 105 m and left 27m

i.e  7x/10-105=27

  7x/10=132

 x=1320/7=160m
