A is thrice as good as workman B and therefore able to finish a job in 60 days less than B. Working together they can do it in how many days?

Reply Like? Yes (1) | No

Rishu 8 years ago

22.5 days

let B completes the job in x days
then, A completes the job in (x-60) days
work done by B in 1 day=1/x
work done by A in 1 day=1/(x-60)
3*(1/x)=1/(x-60)
3x-180=x
2x=180
x=90
so B completes the job in 90 days & A completes it in (90-60)=30 days
working together they can complete the job in 1/(1/90+1/30)=22.5 days

If the numerator of a fraction is increased by 200% and the denominator by 400% the resultant fraction is 3/8. What is the original fraction ?

Reply Like? Yes (1) | No

Rishu 8 years ago

5/8

let numerator and denominator of the original fraction be x & y respectively
then,the original fraction=x/y
(x+2x)/(y+4y)=3/8
or 3x/5y=3/8
or x/y=5/8

Q: Find the sum of the first 40 terms of the series 12 - 22 + 33 - 42 + ......

a) 820 b) -820 c) 870 d) -870

Reply Like? Yes (1) | No

Rishu 8 years ago

b) -820

the whole series is like below:
Sn=12-22+33-42+45-62+66-82+78-120+99-122+111-142+132-162+144-182+165-202+.....
the above series consists of three independent series:
(1) it starts from 12 with a common difference of 33 and has 10 terms
Sn1=12+45+78+111+.....=(10/2)*(2*12+(10-1)*33)=1605
(2) it starts from -22 with a common difference of -20 and has 20 terms
Sn2=-22-42-62-82-.....=(20/2)*(-22*2+(20-1)*(-20))=-4240
(3) it starts from 33 with a common difference of 33 and has 10 terms
Sn3=33+66+99+132+.....=(10/2)*(2*33+(10-1)*33)=1815

thus, Sn=Sn1+Sn2+Sn3=1605-4240+1815=-820

Rishu 8 years ago

D-15.78%

CP of 25 apples at a rate of 8 apples/rupee=(1/8)*25=Rs. 25/8
CP of 35 apples at a rate of 4 apples/rupee=(1/4)*35=Rs. 35/4
CP of 60 apples=25/8+35/4=Rs. 95/8
SP of 60 apples at a rate of 6 apples/rupee=(1/6)*60=Rs. 10
loss=CP-SP=Rs. 15/8
loss%=[(15/8)*100]/(95/8)=15.78%

Devendra Marghade 8 years ago

Loss of 16.66%

CP of 25+35=60 apples is 12 Rs.
SP for 60 apples is 10 Rs.
So % loss=(12-10)*100/12=50/3=16.66
