Joseph's weight is two times the weight of his younger brother. Find Joseph's weight if some of their weights is 63 Kg.​

Answer 1

• let the weight of his younger brother be X

• Therefore his brother's weight=2X

• Therefore by given condition

2X+X=63

3X=63

X=63/3

X=21

Answer 2

Let their weights be 2x and x respectively.

Given,

2x + x = 63

3x = 63

x = 21

Joseph's weight = 2x = 2*21= 42 kg.
