The ratio between two consecutive natural numbers (in ascending order) is reversed if seven is added to the first number and four is added to the second number. The sum of the two consecutive numbers is _______.

A sum of $₹7,740$ is divided between X, Y, and Z such that the ratio of the share of X to the combined share of Y and Z is $4 : 11$ and the ratio of the share of Z to the combined share of X and Y is $1 : 3$. What is the share (in Rs.) of Y?

The ratio of monthly income of P to monthly income of Q is 9: 11, and P's savings are $\frac{100}{3}$ % more than Q's savings. What is the expenditure (in ₹) of P, if the sum of monthly income of P and Q is ₹2,40,000, and expenditure (in ₹) of Q is ₹84000?

In a business partnership among P, Q, R and S, the profit is shared as follows:

$\frac{\text{P's share}}{\text{Q's share}} = \frac{2}{3}$, $\frac{\text{Q's share}}{\text{R's share}} = \frac{4}{5}$, $\frac{\text{R's share}}{\text{S's share}} = \frac{5}{12}$.

If the total profit is ₹24850, the difference (in ₹) of the combined share of profit of P and S and that of Q and R taken together is
