Solutions:
1. D) avg. no. of players who play football and rugby together =1/2 × 30% of 4200 = 630
2. A) number of female players who play lawn tennis = 22% of 2000= 440 ,
Number of male players who play rugby = 13% of 4200 – 10% of 2000 = 346,
Reqd. = 440 – 346 = 94
3. C) number of players who do not play cricket = 40% of 2000= 800
Number of male players who play hockey = 10% of 4200 – 15% of 2000 = 420 – 300 = 120 ,
reqd. ratio = 800 : 120 = 20 : 3
4. B) reqd. number of male players who play football, cricket and lawn tennis together = 77% of 4200 – 75% of 2000 = 3234 – 1500 = 1734
5. A) Number of male who play ruby = 13% of 4200 – 10% of 2000 = 546 – 200 = 346
Total number of players who play Lawn Tennis = 25% of 4200 = 1500
Required percentage = 346/1500 × 100 = 23.06 ≈ 23%
6. D) Strike rate = (Run/Ball)*100=> Run= (S.R * Ball)/100
Let ball Dhoni:Pujara =4x:5x
Run by Dhoni(D)=80*4x/100=32x/10
Run by Pujara=70*5x/100=35x/10
Required %=(35x-32x)/32x *100=9.375%
7. D) Total runs scored by Shikhar in 10 matches = 10*70= 700
Runs scored in 1st seven matches =7*(70-15)=385 (as avg reduces by 15)
Runs scored in last 3 matches=700-385=315(8th , 9th and 10th match)
Minimum run in 10th match means maximum runs in 8th and 9th match.
But run in 8th and 9th matches are below 100, => one is 99 other is 98 (as no run is equal)
Hence run in 10th match=315-(99+98)=118
8. C) Let average=x =>Total run=20x
Balls=20x -600
=>(20x/(20x-600))*100=160 [Strike Rate]
Solve x=80
9. C) Let he played x balls in 1st 8 matches and x balls in last 8 matches.
S.R = Run/Ball *100 => Run=(S.R * Ball*100)
For 1st 8 matches => Run= 80x/100
For last 8 matches=> Run = 96x/100
Total run=16*55=880
=> 80x/100 + 96x/100 =880
x=500
Total balls =2x=1000
10. C) Number of matches played by Rahane = 60x/400 *100 =120
x=8
