Two tailors X and Y are paid a total of 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. 200
Rs. 250
Rs. 300
None of these
Explanation:
Let the sum paid to Y per week be Rs. $ z $.
Then, $ z $ + 120% of $ z $ = 550.
$\Rightarrow z $ +$ \dfrac{120}{100} z $ = 550
$\Rightarrow \dfrac{11}{5} z $ = 550
$\Rightarrow z $ =$ \left(\dfrac{550 \times 5}{11} \right) $ = 250.
