Understand the Problem
The question is asking to determine B's share of earnings given that A and B together earn Rs. 900 and that A's share is half of B's share. It requires understanding of ratios and basic arithmetic to solve it.
Answer
B's share is $600$.
Answer for screen readers
B's share is $600$.
Steps to Solve
- Define Variables
Let B's share be denoted as $B$. According to the problem, A's share is half of B's share, so we can denote A's share as $A = \frac{1}{2}B$.
- Set Up the Equation
Since A and B together earn Rs. 900, we can set up the equation:
$$ A + B = 900 $$
Substituting for $A$:
$$ \frac{1}{2}B + B = 900 $$
- Combine Terms
Combine the terms on the left side of the equation:
$$ \frac{1}{2}B + \frac{2}{2}B = 900 $$
This simplifies to:
$$ \frac{3}{2}B = 900 $$
- Solve for B
To solve for $B$, multiply both sides by $\frac{2}{3}$:
$$ B = 900 \times \frac{2}{3} $$
Calculating this gives:
$$ B = 600 $$
- Conclusion
Thus, B's share is Rs. 600.
B's share is $600$.
More Information
