Ticket from Teresa Boam - Training

I am in Module 2,1 and you have conflicting information relating to back-end ratios in the PDF study guide.Page 22 states FHA back-end rations are 43% and 45% for Energy Efficient. Page 32 you state back-end guidelines for FHA are 41% and 45%. What is the correct back-end ratio for FHA loans 41% or 43%? Thank you
