Answer 2

Let weight of Joseph's younger brother = x Kg

Joseph's weight = 2x kg

A/C to question,

Joseph's weight + weight of Joseph's younger brother = 63 Kg

=> 2x + x = 63 Kg

=> 3x = 63

=> x = 21 Kg

hence, weight of Joseph's younger brother = 21kg

and Joseph's weight = 2 × 21 = 42 Kg

\text{\bf{hence, Joseph's weight = 42 Kg}}hence, Joseph’s weight = 42 Kg

100% correct answer
