The diagonal of a rectangular field is $15\text{m}$ and its area is $108{\text{m}}^2$. What is the cost of fencing the field at $\text{₹}50.50$ per $\text{m}$?

If $x$ is subtracted from each of $17,14,22$ and $18$, then these numbers are in proportion, in this order. What is the mean proportion between $9x$ and $5x$?

The average of $15$ numbers is $56$. The average of the first $8$ numbers is $54.4$ and that of the last $8$ numbers is $56.6$. If the $8^{\text{th}}$ number is excluded, then what is the average of the remaining numbers? (correct to one decimal place)

The value of:
