Study the given table and answer the following questions
Q.
If the difference between the Profits made by Shop A and Shop B on Mouse is equal to the Profit earned by Shop C on Calculator then his Profit percent is?
2500*(139)/100 = Rs 100
2300 = 2200(100+x)/100
X = 50/11%
Q.

25*13 = 325
Q.
Shop A has made Maximum Profit on which article?
Checking by observation
Mouse : 25*13 = 325

Q.
If the total profit made by Shop A, B and C on Hard Disk is Rs.988 then what is the profit of B on Hard Disk?
26*(12+x+15) = 988
X = 11%
Profit = 26*11 = 286

966 – 912 = 54
Direction (Q. 1115) Study the given table and answer the following questions.
Q.
In Infosys, if the number of Female candidates qualified was 87,808 then what is the respective ratio of the number of Qualified Male candidates to the number of Qualified Female candidates in Infosys?
290000*98/100*64/100(F/F+M) = 87808
94080F = 87808M
M/F = 15:14
Q.
In HCL, if the ratio of the number of students Attended to the number of candidates qualified is 8:5, and the number of Males qualified was 88704 then number of Females qualified is?
If the ratio of number of students Attended to number of candidates qualified is 8:5 then percentage of candidates qualified out of attended is 60%
297*96*6*(M/M+13) = 88704
M = 14
Then Females = 297*96*6*13/27 = 82368
Q.
If the difference between the number of Male qualified candidates and the number of Female candidates in Wipro is 5922 then no of candidates attended in Wipro is?
X*94/100*70/100*(1615/31) = 5922
X = 279000
No of candidates attended is 279000*94/100 = 262260
Q.
If the number of candidates qualified in TCS is 7319 more than the number of candidates qualified in CTS then the number of Male candidates qualified is how much more than the number of Female candidates in CTS?
TCS = 312000*98/100*65/100 = 637*312
CTS = 325000*x/100*62/100 =
TCS – CTS = 73190 = 312000* 98/100* 65/100 – 325000* x/100* 62/100
Then x = 95%
CTS (Males – Females) : 325000*95/100*62/100*(1312/25) = 7657
Q.
In TCS females Qualified forms approximately what percent of Qualified Males if no of Males Qualified is 114660?
312000*98/100*65/100*(15/15+x) = 114660
X= 11
% = 11/15*100 = 73.33%

(2850+2800) : (2520+2380)
565: 490
113:98
