Radar Graph Quiz 1

We can represent the above question like this

Country

Average runs

Number of matches

Total Runs

[Average runs * Number of matches]

Australia 

32

5

160

West Indies 

56

3

168

South Africa

25

4

100

Pakistan

62

5

310

Zimbabwe

75

3

225

Total runs

= 160+168+100+310+225

= 963

Runs scored against Pakistan and West Indies

= 168+310

= 478

Hence the answer is
=\frac{478*100}{963}


= 49.64%

Or, approximately 50%

So, total matches

= 5+3+4+5+3

= 20

Total runs

= 160+168+100+310+225

= 963

As he scores 110 not out so now, the total run is

= 963+110

= 1073

As he is not out so the total number of matches is considered is 20

Hence the answer is

= 1073/20

= 53.65

Total runs

= 160+168+100+310+225

= 963

As we know the total angle in a pie chart is 360°

Hence the answer is

=\frac{310*360°}{963}

= 115.88°

Or approximately 115°

If the average runs of Vijay against South Africa would be 20% more, then Vijay’s average run against South Africa is:

=\frac{25*120}{100}

= 30

If the average runs of Vijay against Zimbabwe would be 40% less, then Vijay’s average run against Zimbabwe is:

=\frac{75*60}{100}

= 45

So, Vijay’s total runs against South Africa in 4 matches is

= 30*4

= 120

So, Vijay’s total runs against Zimbabwe in 3 matches is

= 45*3

= 135

Hence the answer is

= (120+135)/7

= 36.42

Or, approximately 35

Let the total work is = LCM(15,20,10,30,12)

= 60 units

We can represent the question like this

Name

Number of days to finish the work

Units of work done per day = (60/number of days)

A

15

4

B

20

3

C

10

6

D

30

2

E

12

5

If, the efficiency of A reduced by 50% then A will do

=\frac{4*50}{100}

= 2 units work in a day

So, A,C,D will do = 2+6+2 = 10 units of work togather

Hence the answer is

= 60/10

= 6 days

So, in 1 day 5 of them will do
= 4+3+6+2+5

= 20 units of work

So, when A,C leave (60-20) = 40 units of work is left

In 3 more days B,D,E will finish

= 3*(3+2+5)

= 30 units of work

So, 40-30=10 units of work is left

So, D will finish the remaining work in

= 10/2

= 5 Days

So, A can do 4 units of work in a day

B and D together can do = 3+2 = 5 units of work together

Hence the answer is

=\frac{(5-4)*100}{5}

= 20%

A,C,D will finish

= 4+6+2

= 12 units job in a day

So, they will finish the work in

= 60/12

= 5 Days

B,E will finish

= 3+5

= 8 units job in a day

So, they will finish the work in

= 60/8

= 7.5 Days

So, x=5

y=7.5

So,
x-y

=5-7.5

= -2.5
