Let the common ratio be \( x \), then:
\[ R = 49x + 29 \]
\[ L = 34x + 46 \]
\[ K = 65x + 30 \]
Substituting \( R, L, \) and \( K \) into the equation:
\[ (49x + 29) + (34x + 46) + (65x + 30) = 6765 \]
Combining like terms:
\[ 148x + 105 = 6765 \]
Subtracting 105 from both sides:
\[ 148x = 6660 \]
Dividing by 148:
\[ x = \frac{6660}{148} = 45 \]
Using the formula for \( L \):
\[ L = 34x + 46 = 34 \times 45 + 46 \]
\[ L = 1530 + 46 = 1576 \]
Thus, the share of Lakshman is 1,576. The correct option is (A).
