Two tailors X and Y are paid a total Rs. 550 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?

Rs. 250

Let Y's weekly pay = ₹x.

Since X is paid 120% of Y's pay,

$X = 1.2x$

The total weekly pay is ₹550:

$1.2x + x = 550$

$2.2x = 550$

$x = \frac{550}{2.2} = 250$

Therefore, Y is paid ₹250 per week.
