Quantitative Aptitude (CCS) Data Table

Read the information below and answer the questions that follow.
Five people A, B, C, D and E took part in a competition which comprises of completing a painting while they are in a running position. The table below shows the time taken by them to complete a painting when they are in static position and their maximum speed. When in running position the time taken by them to complete a painting increased by (60*n) minutes where n is the speed at which they are running at that moment.
Note: Take n in m/s. When we say time is increased by (60*n) minutes, it means that time increased is directly proportional to n.
A person has to start drawing the painting as soon as he starts running.

B started running at (2/3)rd of his maximum speed and continued at the same speed till the end of the race and hence completes the race in 180 minutes. As a result some part of his painting remains incomplete. Find the time required to complete this remaining portion of the painting in static position after he has completed the race.

Explanation:

Time that B will take to complete the painting in running position= 150 + (n*60) minutes
n=2/3*1.5= 1 m/s
Time required to complete the painting=150 + 1*60=210 minutes
So in 180 minutes he completed 180/210 part of the painting= 6/7
Remaining=1/7
in static position B can complete 1 paining in 150 min; so 1/7 paining in 150/7 minutes
