प्रश्न

When Krishna travelled 25 km, he found that `3/5` of his journey was still left. What was the length of the whole journey?

बेरीज

उत्तर

`3/5` of the total journey was left

∴ Journey travelled by him = `1 - 3/5`

`= (5 - 3)/5 = 2/5`

∴ `2/5` of total journey = 25 km

∴ Total journey = `25  "km"  xx 5/2 = 125/2 "km"`

`= 62 1/2` km
