Answer:

She spent 2 hrs.51 min. in studying

Step-by-step explanation:

Given:

Time spent by Puja for doing Maths = 2 3/5 hrs. = 13 /5 hrs.

Time spent by her in reading English book = 1/4 hrs.

Total time spent by her on study = time spend for doing Maths + time spent in reading English book

                                                      = ( 13/5) + ( 1/4)

                                                      = {( 13 × 4 )+(1 × 5)} / 20

                                                       = (52 + 5 ) /20 = 57 /20 =2 17 /20 hrs.

                                                      = 2 hrs. (17 /20) × 60= 2 hrs 51 min.
