Data Interpretation Quiz 6

shape Introduction

What is data interpretation? Data Interpretation or DI refers to the implementation of procedures through which data is reviewed for the purpose of arriving at an inference. Data can be obtained from multiple sources. Example: data from running of industries, census population data etc.
Data Interpretation is one of important topic in Quantitative Aptitude Section. In Data Interpretation Quiz 6 article candidates can find questions with answer. By solving this questions candidates can improve and maintain, speed, and accuracy in the exams. Data Interpretation Quiz 6 questions are very useful for different exams such as IBPS PO, Clerk, SSC CGL, SBI PO, NIACL Assistant, NICL AO, IBPS SO, RRB, Railways, Civil Services etc.
Direction(1-5): Study the following graph carefully and answer the following questions given below.
SPLessons

shape Q1

P and R started the work jointly. A few days later U also joined them and thus all of them completed the whole work in 10 days. All of them were paid total Rs.600. What is the Share of U?
    A. Rs.360 B. Rs.385 C. Rs.240 D. Rs.260

SPLessons

Efficiency of P = 4%
Efficiency of R = 2%
[(4 + 2) × 10] = 60%
The remaining work was done by U = 40%.
40% of 600 = 240

shape Q2

Q and S work together for 5 days, the rest of the work is finished by M in two more days. If they get Rs. 6000 as wages for the whole work, what are the daily wages of Q, S and M respectively?
    A. 200, 250, 300 B. 300, 200, 250 C. 600, 400, 200 D. 600, 400, 500

SPLessons

Q’s 5 days work = 50%
S’s 5 days work = 33.33%
M’s 2 days work = 16.66% [100 - (50 + 33.33)] Ratio of work of Q, S and M = 3: 2: 1
Q’s total share = Rs. 3000
S’s total share = Rs. 2000
M’s total share = Rs. 1000
Q’s one day’s wage = Rs.600
S’s one day’s wage = Rs.400
M’s one day’s wage = Rs.500

shape Q3

The efficiency of L is 25% more than P. L started a work alone and then P joined her 5 days before actual completion of the work. For how many days L worked alone?
    A. 9 B. 11 C. 10 D. 25

SPLessons

Efficiency (L : P) = 5 : 4
Number of days(L : P) = 4x : 5x = 4x : 25
∴ Number of days required by L to finish the work alone = 4x = 4 x 5 = 20.
L and P work together for last 5 days = 5 x 9 = 45%
Efficiency of L = 5% and P’s efficiency = 4%
∴ No. of days taken by L to complete 55% work = [latex]\frac {55}{5}[/latex] = 11days

shape Q4

R started the work and left after some days, when 25% work was done. After it Z joined and completed it working for 25 days. In how many days R and Z can do the complete work, working together?
    A. 6 B. 8 C. 10 D. 20

SPLessons

Efficiency of R = ([latex]\frac {100}{50}[/latex]) = 2%
Rest work = 75%
∴ Efficiency of Z = [latex]\frac {75}{25}[/latex] = 3%
∴ Combined efficiency of R and Z = 5%
∴ Number of days required by R and Z to work together = [latex]\frac {100}{5}[/latex] = 20 days.

shape Q5

T and V started the work. After 3 days Z joined them, who can complete alone the same whole work in 3 days. What is the total number of days in which they had completed the work?
    A. 12 B. 8 C. 6 D. 4

SPLessons

Efficiency of T and V = 11.11 + 5.55 = 16.66%
Work done in 3 days = 3 x 16.66 = 50%
Rest work done by T, V and Z = [latex]\frac {50}{50}[/latex] = 1 day
Work can be completed in 4 days.
