Data Interpretation Ques 29

Question-

Directions : Read the following paragraph carefully and answer the questions given below:

A construction concern has given the details about the number of days taken by five different workers $P, M, V, S$ and $T$ to complete two different works (Work 1 and Work 2). Work 1 is completed by P, M, V, S and T in 7 days, 8 days, 6 days, 5 days and 10 days respectively. Work 2 is completed by $P, M, V, S$ and $T$ in 5 days, 6 days, 8 days, 7 days and 5 days respectively.

The work 1 is completed by $P$ and $M$ together and work 2 is completed by $V$ and $S$ together. What is the difference between total days taken to complete both the work?

(1) $3 \frac{11}{15}$

(2) $2 \frac{15}{29}$

(3) $2 \frac{8}{15}$

(4) $3 \frac{13}{29}$

(5) None of these

Show Answer

Answer: (5)

Solution: (5)

Time taken by $P$ and $M$ in doing work $1 = 1 \div (\frac{1}{7} + \frac{1}{8})$ $= 1 \div (\frac{8 + 7}{56}) = \frac{56}{15}$ days
Time taken by $V$ and $S$ in doing work 2 $= 1 \div (\frac{1}{8} + \frac{1}{7}) = 1 \div (\frac{7 + 8}{56})$ $= \frac{56}{15}$ days

No difference

Required difference $= 0$ days
