Which of the following represents ab=64?
- 8:a=8:b
- a:16=6:4
- a:8=b:8
- 32:a=b:2
- d
-
8/a*8/b=
8A=8B
a/19*6/4
4A=76
A=19
a/8*b/8
8A=8B
A=B
32/a*b/2
64=ab
The ratio of girls and boys in a club is 3:2. Which of the following could be the actual number of members?

If 60% of A=3/4 of B, then A:B is:
- 4:5
- 9:20
- 5:4
- 20:9
- a
-
60% of A=60/100*A=3/5*A=3A/5
3A/5*3B/4
12A/15B
4A/5B
A/B=4/5
A:B=4:5
In an examination 80% candidates passed in English and 85% candidates passed in Mathematics. If 73% candidates passed in both these subjects, then what percent of candidates failed in both the subjects?
- 8
- 15
- 27
- 35
- a
-
Students Passed in English= 80%
Students Passed in Mathematics= 85%
Students Passed in both Subjects=73%
Students Passed at least one Paper=(80+85)-73=92%
Students failed in both Subjects=100-92=08%
1.14 is expressed as a percent of 1.9 is:
- 60%
- 70%
- 80%
- 90%
- a
-
Percentage %=Obtained Value / Total Value*100
%=1.14/1.9*100=0.6*100=60%
Which one of the following number can be removed from the set S=[0,2,4,5,9] without changing the average of set 5?
- 2
- 4
- 5
- 9
- b
-
S=[0,2,4,5,9]
Average=Sum of Terms/Number of Terms
Sum of Terms=0+2+4+5+9=20
Number of Terms=5
Average=20/5=4
Now
Remove one number=4
Sum of Terms=0+2+5+9=16
Number of Terms=4
Average=16/4=4
