A woman reduces her weight in the ratio 7 : 5. What does her weight become if originally it was 84 kg?
Advertisements
उत्तर
Let the reduced weight be x.
Original weight = 84 kg
Thus, we have
84 : x = 7 : 5
`=> 84/x = 7/5`
`=> 84 xx 5 = 7 xx x`
`=> x = (84 xx 5)/7`
`=>` x = 60
Thus, her reduced weight is 60 kg.
