Question

Rajesh solved 80 percent of the questions in an examination correctly, out of 41 questions solved by Rajesh 37 questions are correct and of the remaining questions out of 8 questions, 5 questions have been solved by Rajesh correctly then find the total number of question asked in the examination?

Answer 1

Dear Student:

Assume there are x questions 

⇒No. of questions answered correctly=5x/41

⇒No. of remaining question=8x

 Now,using equations

37 + 5x/41 + 8x = 80% = 4/5 

⇒ 185 + 25x = 164 + 32x 

⇒ 7x = 21 

⇒ x = 3 

Hence,total no. of questions = 41 + 8 x 3 = 65. 

Hope it helps

Thanks
