Answer/Solution
15kg
Steps/Work
Let their weights of x kgs and (x + 10) kgs respectively.
Then, (x + 10) - 5 = 2(x - 5)
⇔ x +5= 2x - 10
⇔ 3x = 15
∴ Present weight of the heavier person = (5 + 10)
= 15kgs.
Answer :15kgs
Then, (x + 10) - 5 = 2(x - 5)
⇔ x +5= 2x - 10
⇔ 3x = 15
∴ Present weight of the heavier person = (5 + 10)
= 15kgs.
