Question:X is 25% more efficient than A and Y is as efficient as B. They worked together for 4 days and left the work due to illness. After that D came to help them and completed the remaining work. In how many days D completed the work?

Correct

A works 20% work in 8 days

A works 100% in 8/20 * 100 = 40 days

X is 25% more efficient than A. So X can complete the work in=

125 * D = 100 * 40

D= 32

X can complete the work in 32 days

B works 15% in 3 days

B works 100% in 3/15 * 100 = 20 days

Y can complete the work in 20 days

They worked for 4 days. In these days they worked= 4/32 + 4/20 = 13/40

Remaining work= 1- 13/40 = 27/40

D works 30% in 15 days

D worked 100% in= 15/30 * 100 = 50 days

D worked 27/40 work in 15/30 * 50 = 33.75 days

Incorrect

A works 20% work in 8 days

A works 100% in 8/20 * 100 = 40 days

X is 25% more efficient than A. So X can complete the work in=

125 * D = 100 * 40

D= 32

X can complete the work in 32 days

B works 15% in 3 days

B works 100% in 3/15 * 100 = 20 days

Y can complete the work in 20 days

They worked for 4 days. In these days they worked= 4/32 + 4/20 = 13/40

Remaining work= 1- 13/40 = 27/40

D works 30% in 15 days

D worked 100% in= 15/30 * 100 = 50 days

D worked 27/40 work in 15/30 * 50 = 33.75 days

Correct

C worked 25% in 6 days

C worked 100% in 6/25 * 100 = 24 days

In 6 days C worked 6/24 work

Remaining work= 1- 6/24 = 1- ¼ = ¾

D worked 30% in 15 days

D worked 100% in 15/30 * 100 = 50 days

D completed ¾ th part work in ¾ * 50 days = 37.5 days

Incorrect

C worked 25% in 6 days

C worked 100% in 6/25 * 100 = 24 days

In 6 days C worked 6/24 work

Remaining work= 1- 6/24 = 1- ¼ = ¾

D worked 30% in 15 days

D worked 100% in 15/30 * 100 = 50 days

D completed ¾ th part work in ¾ * 50 days = 37.5 days

Question:A and D started doing the work. After 10 days they both left and B joined the work. He completed his part of work. Now the remaining work was completed by P in 18 days. In how many days P can complete the whole work?

Correct

A worked 20% in 8 days

A worked 100% in 8/20 * 100= 40 days

D worked 30% in 15 days

D worked 100% in 15/30 * 100= 50 days

In 10 days they worked= 10/40 + 10/50 = 9/20

B completed 15% work

Total work done by three= 9/20 + 3/20 = 3/5

Remaining work= 1 – 3/5 =2/5

2/5 work completed by P in 18 days

P can complete a work in 18 * 5/2 = 45 days

Incorrect

A worked 20% in 8 days

A worked 100% in 8/20 * 100= 40 days

D worked 30% in 15 days

D worked 100% in 15/30 * 100= 50 days

In 10 days they worked= 10/40 + 10/50 = 9/20

B completed 15% work

Total work done by three= 9/20 + 3/20 = 3/5

Remaining work= 1 – 3/5 =2/5

2/5 work completed by P in 18 days

P can complete a work in 18 * 5/2 = 45 days

Question:P is 20% less efficient than B. Q is 50% less efficient than D. R is 50% more efficient than E. In how many days P, Q and R can complete the work together?

Correct

B completes the work in= 3/15 * 100= 20 days

P is 20% less efficient than B. So P can complete work=

80 * D= 100 * 20

D= 25 days

D completes the work in= 15/30 * 100= 50 days

Q is 50% less efficient than D. So Q completes the work=

50 * D= 100 * 50

D= 100 days

E can complete the work= 12/50 * 100= 24 days

R is 50% more efficient than E. E completes work in=

150 * D= 100* 24

D= 16 days

P+Q+R = 1/25 + 1/100+ 1/16 = 45/400 = 9/80

Incorrect

B completes the work in= 3/15 * 100= 20 days

P is 20% less efficient than B. So P can complete work=

80 * D= 100 * 20

D= 25 days

D completes the work in= 15/30 * 100= 50 days

Q is 50% less efficient than D. So Q completes the work=

50 * D= 100 * 50

D= 100 days

E can complete the work= 12/50 * 100= 24 days

R is 50% more efficient than E. E completes work in=
