    40:00 can be done simply as:

    And for 100% t will be =4 min
    Now for 33% i.e. 1/3 of 100% t will be 1/3 of t or 1/3×4=1.33min. and this is the required answer

    41:00 , it can be done in a even more simpler way time taken for 50 percent completion = 2 min.
    for 1 percent completion = 2/50 min.
    so, for 33.33 percent completion = 2/50 * 33.33 = 1.333 min.

    42:00 In that question if we can calculate time take for 1 % it is easy to calculate time for 33.33% by multiplying it with 33.33% .
    Eg. 4 min for 100% so 0.04 for 1% implies 0.04 × 33.33 = 1.33 ans.

    So 33.33% gets completed in ( 2÷50 )×33.33 ..... you will get your answer

    40:00 we can also solve by finding out the time taken for per percent completion = 2min/50= 1/25 min per 1% product formation(completion).
    Now we hv to find out time taken for completion of 33.33% :-
    33.33×1/25 = 1.333.. mins ~ 1.34 mins(ans).
