## Data Interpretation (Time & Work) Problem 1 :

**A task requires appropriate skills in designing. There are five levels of designing skills. The level ****of ****skills and corresponding number of days taken by a person ****of ****that skill level is tabulated below. There are tour groups of people. The information about the number ****of ****people and their skill level is provided in the ****Bar ****chart below.**

**1) If ****three Level-4 skilled and two Level-2 skilled people started working together on a task and all ****of ****them left ****after ****working for 2 days, then how long would it take three Level-I and one Level-5 people to finish the remaining task****?
**1) 7(11/65) 2) 7(12/65) 3) 7(7/65) 4) 7(1/13) 5) 7(21/65)

**2****) Assuming ****the number ****of ****days given here is applicable for 8 working hours a day. Four Level-3 people and three Level-4 people started working. In the first three days, Level-3 skilled people worked 2 hours extra every day and during extra working hours their efficiency was 50% more than their actual efficiency. Find the total number ****of ****days taken to complete the task. ****
**1) 3(49/82) 2) 15(11/24) 3) 6(13/24) 4) 3(59/82) 5) 2(1/7)

**3) ****What is the difference between the number of days taken by all the people ****of Group-P ****and ****Group-Q ****to complete the task? ****
**1) 21/209 2) 63/418 3) 21/106 4) 63/209 5) None

**4) Assuming ****Group-E comprises ****of ****all the Level-4 and Level-5 persons ****of ****the tour groups while Group-F comprises ****of ****all the Level-2 and Level-3 persons of the tour groups It Group-E completes 70% ****of ****the task and then the remaining task is completed by Group-F, then what is the total number of days that it would take to complete the task? **

1) 1(7064/9581) 2) 1(7464/9581) 3) 1(7264/9581) 4) 1(7764/9581) 5) None

**5) ****What is the difference between the number of days taken by all the people ****of ****Group-A and Group-B to complete the task?**

**DATA INTERPRETATION – ****Time, Distance and Speed**

**Following Pie chart shows distances between some places given such as A – B means distance from Place A to B (in kms) And the following table shows the difference between time taken by P and Q respectively to travel.**

**1****) Car Q ****is ****travelling with 50 km/h. ****Car ****P starts ****from place ****D ****w****ith ****its normal speed and after reaching ****E ****it reduces ****its speed ****to ****2/3****rd**** till halfway from E ****to ****F ****and ****then increases ****its ****subsequent ****speed 20% and reached ****F. ****Find the ****ratio ****of time taken by ****P in ****given journey to the ****time ****taken ****by P ****to go ****from D ****to ****F without change ****in ****speed.(Speed of Q is greater than P)
**1) 32 : 21 2) 16 : 17 3) 41 : 32 4) 53 : 63 5) None

**2****) If ****speed ****of ****car ****P is ****Increased ****by ****20% and ****speed ****of car ****Q ****is ****decreased ****by ****11(1/9)% and they ****both ****start from place B ****at the same ****time ****then find the sum ****of ****time taken them when they reach place ****D. Also, ****given ****that with ****changed ****speeds, ****time taken by ****Q ****to ****go ****from ****E ****to ****F ****is 9/4 times the time taken ****by ****P** **to go ****from A ****to B****.
**1) 17 hours 17 minutes 2) 12 hours 17 minutes

3) 2 hours 27 mins 4) 12 hours 27 minutes

**3****) If ****speed of ****P ****and ****Q ****is reduced by 20% and ****11(1/9) ****% ****respectively, ****then the ****difference ****of time taken ****b****y** **them to travel from ****B to C increases ****by ****87.5%. If, P ****Starts from A**** and Q starts from F then ****between ****which ****places ****will ****they meet ****if ****they are ****travelling with ****reduced speeds as given speed ****of Q ****is greater than ****the ****speed ****of P.
**1) A and B 2) B and C 3) C and D 4) D and E 5) E and F
