(a) 50%             (b) 45%             (c) 40%             (d) 35%              (e) None of these

Answer & Explanation

1.(b)Total valid votes=6000-6000X(25/100)

=6000-1500

=4500

Votes obtained by Bhiku=65% of 4500

=(13/20)X4500=2925

Votes obtained by Mhatra=4500-2925=1575

2.(b)After 1st year, Population=10000+1000X10%=11000

After 2nd year population=11000-11000X5%=10450

After 3rd year population=10450+10450X20%=12540

3.(c)Suppose total candidates=200

Total appeared Candidates=200-25% of 200=150

30% of 200=60 students failed

Obtained marks by failed students=60X13=780

10% of 200=20 students passed

Obtained marks by passed students=20X33=660

35% of student=70, Score=70X60=4200

Average of Class=(Total Score)/(Total appeared Candidates)=(780+660+4200)/150=37.6

4.(a)Suppose there are 100x books on 2nd row.

Then, 1st row=125x

2nd row=100x

3rd Row=75 x

Total 125x+100x+75x=300x=600

x=2

So, on 1st row =125X2=250 books.

5.(d)Insufficient information, Because we can’t assume last year data to calculate current year%

6. (c)Percentage of people who were not Indian=[((700+500+800)-(700X20%+500X40%+800X10%))/2000)]X100

=79%

7.(b) Let total are be 100%

After 20% wastage, 80% remains

And, of remaining 80%, 25% are pure iron I.e. 20%

So, 20%=80,000 kg

1%=4000 kg

100%=4,00,000 kg

8.(c)  4/5 is actually nothing but 80% [therefore 80/100=4/5]

80% promised to vote for Sonia, but actually voted=72%

20% promised to vote for Sushma, but actually voted=16%\

Because, 72%=216

1%=3

Therefore, [Totat polling=72+16=88%=88X3=264

9.(b) 100(50% increase sales increase)  =150 = (? % of price drop) = 82.5 [Final sales]

Required price Drop=(67.5/150)X100=45%

45% of 250=(9/20)X250=112.5

10.(d) Share of Honda=[100-(15+50)]% =35%
