Answer to Question #165429 in Algebra for Riona Rodrigues

Question

John is carrying 2kg more than than his sister, and the sum of their weights is 21 years. Find the weight they are carrying. 

Answer 1

Ans:-

Let the weight carried by his sister$=$ $x$ kg

so weight carried by john$=$ $x+2$ kg

Now according to question

$\Rightarrow$ $x+x+2=21$

$\Rightarrow 2x=19$

$\Rightarrow$ $x=9.5$ kg

Hence the weight carried by his sister is 9.5 kg and weight carried by John is 11.5 kg
