Number of students in class 8th of school A = 400*(125/100) = 500
Number of passed girls in class 6th of school E = 230*(21/23) = 210
Required ratio = 500 : 210 = 50 : 21
- The total number of failed boys in school A and F together is approximately what percent of the total number of passed girls in school B and E together?
A) 30%
B) 48%
C) 37%
D) 25%
E) 45%
View Answer
Option C
Solution:
Number of failed boys in school A = 240*(1/4) = 60
Number of failed boys in school F = 500*(9/50) = 90
Total number of failed boys = 60 + 90 = 150
Number of passed girls in school B = 200
Number of passed girls in school E = 210
Total number of passed girls = 200 + 210 = 410
Required % = (150/410)*100 = 36.58% = 37%(approx.)

- The selling price of fan and cooler together is approximately what percent of the selling price of T.V. and radio together?
A) 88%
B) 96%
C)100%
D) 80%
E) 150%
View Answer
Option B
Solution:
CP of fan = (12/100)*72000 = 8640
Profit% = 25%
SP of fan = (8640*125)/100 = 10800
CP of cooler = (18/100)*72000 = 12960
Profit% = 48%
SP of cooler = (12960*148)/100 = 19180.80
Total SP of fan and cooler together = 10800 + 19180.80 = 29980.80
CP of TV = (21/100)*72000 = 15120
Profit% = 42%
SP of TV = (15120*142)/100 = 21470.40
CP of radio = (10/100)*72000 = 7200
Profit % = 36%
SP of radio = (7200*136)/100 = 9792
Total SP of TV and radio = 21470.40 + 9792 = 31262.40
Required % = (29980.80/31262.40)*100 = 95.9% = 96%(approx.)

E) 1457.8
View Answer
Option D
Solution:
CP of LED = (26/100)*72000 = 18720
Profit% = 28%
SP of LED = (18720*128)/100 = 23961.60
SP of TV = 21470.40
Required difference = 23961.60 – 21470.40 = 2491.20
- The selling price of fan is approx. what percent of the selling price of watch ?
A) 85%
B) 75%
C)90%
D) 70%
E) 115%
View Answer
Option A
Solution:
CP of fan = (12/100)*72000 = 8640
Profit% = 25%
SP of fan = (8640*125)/100 = 10800
CP of watch = (13/100)*72000 = 9360
Profit % = 35%
SP of watch = (9360*135)/100 = 12636
Required % = (10800/12636)*100 = 85.47% = 85%
- The marked price of radio is approx. what percent of the selling price of LED if 20% discount is available on radio?
A) 55%
B) 51%
C)45%
D) 36%
E) 44%
View Answer
Option B
Solution:
CP of radio = (10/100)*72000 = 7200
Profit% = 36%
SP of radio = (7200*136)/100 = 9792
Discount on radio = 20%
MP of radio = (9792/80)*100 = 12240
CP of LED = (26/100)*72000 = 18720
Profit% = 28%
SP of LED = (18720*128)/100 = 23961.60
Required % = (12240/23961.60)*100 = 51.08% = 51%
