Question

If the weight of Robert and Heather are in the ratio of 5:3. If they differ by 20. Find their weight

Answer 1

Step-by-step explanation:

Let weight of Robert be 5×x units =5x units

Weight of Heather =3×x units =3x units

Their weights differ by 20 units

By condition

5x-3x = 20

2x = 20

x = 20/2

x = 10

Weight of Robert = (5×10) units =50 units

Weight of Heather = (3×10) units =30 units
