Answer 1

Time taken by Mansi = 3h 40min

Meghna took 55 minutes less than Mansi

Meghna took = 3h 40min - 55 min = 2h 45 min
_____________
If you can't subtract directly, convert everything into minutes and subtract.
3h 40min = 3×60 + 40 = 220 min

220 min - 55 min = 165 min = 2×60 + 45 = 2h 45

Amrita took 1h 35 min more than Meghna

So meghna took = 2h 45min + 1h 35 min = 3h 80 min = 4h 20 min

So amrita took 4h 20min
