Answer Key

(A+B)’s one day work=1/80;

(B+C)’s one day work=1/60;

(C+D)’s one day work=1/40;

(D+E)’s one day work=1/20

A’s one day work=1/120

Now, According to question,

B’s one day work=1/80-1/120=1/240

C’s one day work=1/60-1/240=1/80

D’s one day work=1/40-1/80=1/80

E’s one day s work=1/20-1/80=3/80

1.According to question,

(A+B+C)’s one day work=1/120+1/240+1/80=(2+1+3)/240=6/240=1/40

Required Answer, E alone works to finish,

E=(1/40)/(3/80)=1/40×(80/3)=2/3 of the work

Ans=c)2/3

2.According to question,

(A+B+C)’s one day work=1/120+1/240+1/80=(2+1+3)/240=6/240=1/40

Required Answer, E alone works to finish,

E=(1/40)/(3/80)=1/40×(80/3)=2/3 of the work

Ans=c)2/3

3.A’s one day work=1/120;

C’s one day work=1/80;

D’s one day work=1/80

According to question,

work done in first 3 days,

=1/120+1/80+1/80=(2+3+3)/240=8/240=1/30

Time taken to complete 1/30 part of work=30 days

Required Answer, (Time taken to complete the whole work)

=3×30=90 days

Ans=a) 90 days

4.According to question,

A’s one day work=90% of 1/120=90/100×1/120=3/400

B’s one day work=75% of 1/240=75/100×1/240=1/320

C’s one day work=80% of 1/80=80/100×1/80=1/100

(A+B+C)’s one day’s work=3/400+1/320+1/100=(12+5+16)/1600=33/1600

Hence, time taken by them to complete the work=1600/33=48 16/33

Ans=c) 48 16/33 days.

5.Time taken to complete the work by C

=80×4=320 days

Time taken to complete the work by

D=80×100/40=200 days

Time taken to complete the work by E

=800/3×3=800 days

6.Number of students attended chess, hockey and cricket from school C =14%+41%+12%=67%

Number of students attended football, cricket and tennis from school E= 20%+25%+20%=65%

Total students in school E= 160

67% of School C = 65% of school E

67% of school C=65/100×160=104

Total students in school C =104/67×100=155.22≈155

Students attended tennis from School C=20% of 155

=20/100 ×155=31

7.Number of students attended hockey tournament from school A=15% of school A

Number of students attended football and

Cricket tournament from school D = 37% of school D

15% of school A= 37% of school D

Required percentage =(school D total )/(school A total)×100

=(15/37)A /A×100=15/37×100=40 20/37%

8.Number of students attended football from B =52

Number of students attended hockey from B=52/25×21=44

Number of students attended chess tournament from school C=15+52/25×11=38

Number of students attended tennis from school C=38/14×20=54

Required percentage =(54-44)/54×100=19% (approx.)

9.Difference between the number of students who attended football and number of students who attended cricket from school E = (25%-20%) = 5% of school E

Total students from school E=25/5×100=500

Total students from school B = 500×1.4=700

Number of students attended football from school B=25/100×700=175

10.Number of students attended tennis from school C=80

Total number of students from school C=80/20×100=400
