11Arrrre, this kinda shit kept happening with us too.but we were in class 5 then!
Actually,these class 5 books are printed by people who cant even read their own mother tongue, and written by people who made "silly mistakes" while copying it from someone else's book.so this was bound to happen.so most of us are accustomed to dismissing every problem they find a bit tricky as a printing error.Bad habit.
but, HOW OLD IS YOUR SIS?i mean - you must be quite the angry young man by now - but ur sis is in class 5?how many times did the poor fella fail?she has my sympathies, btw.tell her to work hard and be a good elder brother.
