Number of maths problems Yan has finished = 3/5 of 45
                                                                        = 27 maths problems.
Number of maths problems left to be solved = 45 - 27 = 1 8
Each math problem takes 1 4/5 of a minute to solve =9/5 minutes to solve
So, time taken to solve 18 problems = 9/5 X 18
                                                           = 32.4 mins
                                                             = 32 minutes approx
So Yen will take 32 minutes approximately to solve the rest of the pproblems

Hope this answer helped you

time taken for each question 9/5 minutes .
he complete 3/5 x 45 questions
e.g 27 questions complete by Yen
rest questions = 45 -27 = 18

now ,
time taken for solving 18 questions = 18 x 9/5 = 162/5 = 32.4 minutes
hence approximately Yen will take time = 32 minutes .
