Answer:
ohk guys lets solve ☺
Step-by-step explanation:
Total questions=60
questions could not solve= 1/6×60=10
therefore, questions solved=60-10=50
Questins solved and were wrong=1/5 of question solved=1/5×50=10
so, correct answer she gave = total - ( could not solved +wrong answer)
=60-(10+10)=40 questions...
Hope it helps!!!☺☺
