Identify the given values and ratios

We are given the total amount to be distributed as $\text{₹}2,400$ and the ratio of shares of A and B as $7:5$.

$\text{Total Amount} = \text{₹}2,400, \quad \text{Ratio} = 7:5$

Calculate the sum of the ratio parts

The total number of parts in the ratio is the sum of the parts for A and B: $7 + 5 = 12$.

$\text{Sum of parts} = 7 + 5 = 12$

Find the value of one part

Divide the total amount by the sum of the ratio parts to find the value of a single part: $\frac{2400}{12} = 200$.

$\text{1 part} = \frac{2400}{12} = \text{₹}200$

Calculate the share of B

Since B's share corresponds to $5$ parts, multiply the value of one part by $5$: $5 \times 200 = 1000$.

$\text{Share of B} = 5 \times 200 = \text{₹}1,000$
