Two employees 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.350",
"Rs.300",
"Rs.200",
"Rs.250"
] | D | Let the amount paid to X per week = x
and the amount paid to Y per week = y
Then x + y = 550
But x = 120% of y = 120y/100 = 12y/10
∴12y/10 + y = 550
⇒ y[12/10 + 1] = 550
⇒ 22y/10 = 550
⇒ 22y = 5500
⇒ y = 5500/22 = 500/2 = Rs.250

21 friends went to a hotel and decided to pay the bill amount equally. But 20 of them could pay Rs. 30 each as a result 21st has to pay Rs. 200 extra than his share. Find the amount paid by him. | [
"None",
"120",
"110",
"220"
] | A | Explanation:
Average amount paid by 20 persons = Rs. 30
Increase in average due to Rs. 200 paid extra by the 21st men = Rs. 200/20= Rs. 10
Therefore, Average expenditure of 21 friends = Rs. 30 + Rs. 10 = Rs. 40
Therefore, Amount paid by the 21st men = Rs. 40 + Rs. 200 = Rs. 240
