Data Interpretation MCQ -3 - Question 1

### Study the following graph carefully to answer the given questions Down Stream Distance = 200 km                      Up Stream Distance = 300 km A boatman rows down stream at 6kmph on Wednesday. Find the speed of upstream and Speed of current?

Detailed Solution for Data Interpretation MCQ -3 - Question 1

Downstream Speed = 6kmph
Upstream Speed = 8kmph – 6kmph = 2kmph
Speed of Current = (6-2)/2 = 2kmph

Data Interpretation MCQ -3 - Question 2

### Study the following graph carefully to answer the given questions Down Stream Distance = 200 km                      Up Stream Distance = 300 km A boatman rows up stream at 4kmph, 2 kmph and 8 kmph on Monday, Wednesday and Thursday respectively. Then find the ratio between the down stream speed of boat on Monday, Wednesday, and Thursday together and the rate of current on the same days together?

Detailed Solution for Data Interpretation MCQ -3 - Question 2

Downstream Speed of boat on Monday = 10 – 4 = 6kmph. similarly Downstream Speed of boat on Wednesday and Thursday = 6 kmph, 16kmph
Rate of current = 1kmph, 2kmph and 4kmph
Ratio = 28:7 = 4 : 1

Data Interpretation MCQ -3 - Question 11

(Q.no: 11-15). Refer to the table and answer the given questions.
NA refers the data which is not needed for a particular question. The number of working days of A, B, C, D is given below and some of them are missing. Take the data of the first row for the first question and the second row for the second question and so on.

A started a work alone and then B joined her 5 days before actual completion of the work. For how many days A worked alone?

Detailed Solution for Data Interpretation MCQ -3 - Question 11

Efficiency (A : B) = 5 : 4
Number of days(A : B) = 4x : 5x = 4x : 25
∴ Number of days required by A to finish the work alone = 4x
= 4 x 5 = 20.
A and B work together for last 5 days = 5 x 9 = 45%
Efficiency of A = 5% and B’s efficiency = 4%
∴ No. of days taken by A to complete 55% work = 55/5 = 11days

Data Interpretation MCQ -3 - Question 12

(Q.no: 11-15). Refer to the table and answer the given questions.
NA refers the data which is not needed for a particular question. The number of working days of A, B, C, D is given below and some of them are missing. Take the data of the first row for the first question and the second row for the second question and so on.

Working together B and C take 50% more number of days than A, B and C together take and A and B working together, take 8/3 more number of days than A, B and C take together. If A, B and C all have worked together till the completion of the work and B has received Rs.120 out of total earnings of Rs. 480 then in how many days did A, B and C together complete the whole work?

Detailed Solution for Data Interpretation MCQ -3 - Question 12

The days ratio of (A + B + C) : (B + C) = X:3X/2 = 2X:3x;
Efficiency ratio = 3X:2X
Efficiency of A = x.
(480/3X) = Rs.160
Amount received by B = Rs.120 & C = 200
160:120:200 =4:3:5
1/4:1/3:1/5= 15:20:12;
(1/15+1/12+1/20)*Y = 1
Y = 5 days

Data Interpretation MCQ -3 - Question 13

(Q.no: 11-15). Refer to the table and answer the given questions.
NA refers the data which is not needed for a particular question. The number of working days of A, B, C, D is given below and some of them are missing. Take the data of the first row for the first question and the second row for the second question and so on.

All of them started to work together but A leaves after 4 days. B leaves the job 3 days before the completion of the work. How long would the work last?

Detailed Solution for Data Interpretation MCQ -3 - Question 13

Let the work lasted for x days,
A’s 4 day’s work + B (x – 3) day’s work + C’s x day’s work = 1
⇒ (4/16) + (x – 3) / (64/5) + x/32 = 1
⇒ 5(x – 3)/64 + x/32 = 1 – 1/4
⇒ [5(x – 3) + 2x] / 64 = 3/4
⇒ 7x – 15 = 48
∴ x = (48 + 15)/7 = 63/7 = 9 days

Data Interpretation MCQ -3 - Question 14

(Q.no: 11-15). Refer to the table and answer the given questions.
NA refers the data which is not needed for a particular question. The number of working days of A, B, C, D is given below and some of them are missing. Take the data of the first row for the first question and the second row for the second question and so on.

C started the work and left after some days, when 25% work was done. After it D joined and completed it working for 25 days. In how many days C and D can do the complete work, working together?

Detailed Solution for Data Interpretation MCQ -3 - Question 14

Efficiency of C = (100/50) = 2%
Rest work = 75%
∴ Efficiency of D = 75/25 = 3%
∴ Combined efficiency of C and D = 5%
∴ Number of days required by C and D to work together = 100/5 = 20 days.

Data Interpretation MCQ -3 - Question 15

(Q.no: 11-15). Refer to the table and answer the given questions.
NA refers the data which is not needed for a particular question. The number of working days of A, B, C, D is given below and some of them are missing. Take the data of the first row for the first question and the second row for the second question and so on.

B and C started the work. After 3 days D joined them. What is the total number of days in which they had completed the work?

Detailed Solution for Data Interpretation MCQ -3 - Question 15

Efficiency of B and C = 11.11 + 5.55 = 16.66%
Work done in 3 days = 3 x 16.66 = 50%
Rest work done by B, C and D = 50/50 = 1 day
Work can be completed in 4 days.
