Answer


1. Option B

By observing the table, we can predict the answer as either One or Two.
Total no. of matches played by Australia = 2 * match won by Srilanka
= 2*80 = 160
No. of matches won by Australia = 160- (43+12) =105 (> 100)
Total no. of matches won by South Africa= 475- (105+100+90+80)
= 100 (not greater than 100)
Only Australia has won more than 100 matches, so the answer is one.

2. Option C

Let matches won by Australia be x
Let matches played by Srilanka be y

7(100 +x) = 6(162+y)
700 + 7x = 972 + 6y
7x – 6y = 972 – 700
7x – 6y = 272 -----------------(1)
Let the matches played by Australia be z
Matches lost by Srilanka = 2*44=88

z+150= 3(135)
z = 405 – 150 = 255 (matches played by Australia)
Matches won by Australia (x) = z – (43 + 12) = 255-(43+12) =200
Sub x= 200 in eqn. (1)
7(200) – 6y = 272
1400 -6y = 272
6y= 1128
Y = 188 (matches played by Srilanka)
Therefore, matches draw by Srilanka= 188- (80 +88) =20 (ans)

3. Option A

No. of matches draw by India = (10/100)* 100 = 10
No. of matches Played by India =100 + 44 +10 = 154 (ans)

4. Option E

No. of matches draw by Pakistan= 150- (90+0) = 60
% of matches draw by Pakistan = (60/150)* 100 =40 %
% of matches lost by South Africa = (47/162) * 100 = 29 %
Difference = 40 – 29 = 11(ans)

5. Option D

Matches played by India =100+44 =144
Matches played by Pakistan = 150
Matches played by South Africa = 162
Matches lost by India =44
Matches lost by Pakistan = 150 – 90 = 60
Matches lost by Australia = 43
