Question 1. Two Tailors X And Y Are Paid A Total Of Rs. 550 Per Week By Their Employer. If X Is Paid one hundred twenty Percent Of The Sum Paid To Y, How Much Is Y Paid Per Week?
Answer :
Let, the sum paid to Tailor X according to week be Rs. X
and the sum paid to Tailor Y consistent with week be Rs. Y
Given, tailors X and Y are paid a total of Rs. 550 consistent with week
=> X + Y = 550 ---> eqn (1)
Given, X is paid a hundred and twenty percent of the sum paid to Y
=> X = one hundred twenty % of Y
=> X = (120 / a hundred) * Y
=> X = (6 / five) * Y
On substituting this price for X in eqn (1), we get
=> (6 / 5) * Y + Y = 550
=> (6Y + 5Y) / five = 550
=> 11Y = 550 * 5
=> 11Y = 2750
=> Y = 2750 / eleven
=> Y = 250 Rs.
Thus, the sum paid to Tailor Y in line with week be Rs. 250
