days

Answer:_______________

Kumar complete a work in 8 days, where as a Tulasi can complete it in only24 days. If they work together, in how many days, can the work be completed

Answer: 6days

SOLUTION 1 :

Given :

Kumar can complete a work in 8days

work done by Kumar in one day = $\frac{1}{8}$

Tulasi can complete it in 24days

work done by Tulasi in one day = $\frac{1}{24}$

Work done by Kumar and Tulasi together in one day

= $\frac{1}{8}$ + $\frac{1}{24}$

1x3	+	1	=	3	+	1	=	4
8x3	+	24	=	24	+	24	=	24

work done by both, in one day = $\frac{1}{6}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{6}$ days = 6 days.

Sriram complete a work in 4 days, where as a Indra can complete it in only12 days. If they work together, in how many days, can the work be completed

Answer: 3days

SOLUTION 1 :

Given :

Sriram can complete a work in 4days

work done by Sriram in one day = $\frac{1}{4}$

Indra can complete it in 12days

work done by Indra in one day = $\frac{1}{12}$

Work done by Sriram and Indra together in one day

= $\frac{1}{4}$ + $\frac{1}{12}$

1x3	+	1	=	3	+	1	=	4
4x3	+	12	=	12	+	12	=	12

work done by both, in one day = $\frac{1}{3}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{3}$ days = 3 days.

Balaji complete a work in 4 days, where as a Ponnalagu can complete it in only12 days. If they work together, in how many days, can the work be completed

Answer: 3days

SOLUTION 1 :

Given :

Balaji can complete a work in 4days

work done by Balaji in one day = $\frac{1}{4}$

Ponnalagu can complete it in 12days

work done by Ponnalagu in one day = $\frac{1}{12}$

Work done by Balaji and Ponnalagu together in one day

= $\frac{1}{4}$ + $\frac{1}{12}$

1x3	+	1	=	3	+	1	=	4
4x3	+	12	=	12	+	12	=	12

work done by both, in one day = $\frac{1}{3}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{3}$ days = 3 days.

Karna complete a work in 4 days, where as a Swathi can complete it in only12 days. If they work together, in how many days, can the work be completed

Answer: 3days

Swathi can complete it in 12days

work done by Swathi in one day = $\frac{1}{12}$

Work done by Karna and Swathi together in one day

= $\frac{1}{4}$ + $\frac{1}{12}$

1x3	+	1	=	3	+	1	=	4
4x3	+	12	=	12	+	12	=	12

work done by both, in one day = $\frac{1}{3}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{3}$ days = 3 days.

Sriram complete a work in 8 days, where as a Poovazhagi can complete it in only24 days. If they work together, in how many days, can the work be completed

Answer: 6days

work done by Poovazhagi in one day = $\frac{1}{24}$

Work done by Sriram and Poovazhagi together in one day

= $\frac{1}{8}$ + $\frac{1}{24}$

1x3	+	1	=	3	+	1	=	4
8x3	+	24	=	24	+	24	=	24

work done by both, in one day = $\frac{1}{6}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{6}$ days = 6 days.

Barathan complete a work in 8 days, where as a Chellamal can complete it in only24 days. If they work together, in how many days, can the work be completed

Answer: 6days

Barathan can complete a work in 8days

work done by Barathan in one day = $\frac{1}{8}$

Chellamal can complete it in 24days

work done by Chellamal in one day = $\frac{1}{24}$

Work done by Barathan and Chellamal together in one day

= $\frac{1}{8}$ + $\frac{1}{24}$

1x3	+	1	=	3	+	1	=	4
8x3	+	24	=	24	+	24	=	24

work done by both, in one day = $\frac{1}{6}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{6}$ days = 6 days.

Sriram complete a work in 24 days, where as a Ramani can complete it in only72 days. If they work together, in how many days, can the work be completed

Answer: 18days

SOLUTION 1 :

Given :

Sriram can complete a work in 24days

work done by Sriram in one day = $\frac{1}{24}$

Ramani can complete it in 72days

work done by Ramani in one day = $\frac{1}{72}$

Work done by Sriram and Ramani together in one day

= $\frac{1}{24}$ + $\frac{1}{72}$

1x3	+	1	=	3	+	1	=	4
24x3	+	72	=	72	+	72	=	72

work done by both, in one day = $\frac{1}{18}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{18}$ days = 18 days.

Chidambaram complete a work in 28 days, where as a Savithri can complete it in only84 days. If they work together, in how many days, can the work be completed

work done by Chidambaram in one day = $\frac{1}{28}$

Savithri can complete it in 84days

work done by Savithri in one day = $\frac{1}{84}$

Work done by Chidambaram and Savithri together in one day

= $\frac{1}{28}$ + $\frac{1}{84}$

1x3	+	1	=	3	+	1	=	4
28x3	+	84	=	84	+	84	=	84

work done by both, in one day = $\frac{1}{21}$

Number of days requrired to complete the work by both together

= 1/ $\frac{1}{21}$ days = 21 days.

Aravindh complete a work in 12 days, where as a Keerthi can complete it in only36 days. If they work together, in how many days, can the work be completed

Answer: 9days

SOLUTION 1 :

Keerthi can complete it in 36days

work done by Keerthi in one day = $\frac{1}{36}$

Work done by Aravindh and Keerthi together in one day

= $\frac{1}{12}$ + $\frac{1}{36}$

1x3	+	1	=	3	+	1	=	4
12x3	+	36	=	36	+	36	=	36
