Question
'Ramesh' can complete a work in 40 days. He started the
work and left after 24 days from starting. The remaining work was done by 'Suresh' in 30 days. Find the time taken by 'Suresh' to complete 75% of the work.Solution
ATQ,
Fraction of work completed by 'Ramesh' = (24/40) = (3/5)
Remaining work = 1 - (3/5) = (2/5)
Time taken by 'Suresh' to complete (2/5)th of the work = 30 days
Time taken by 'Suresh' to complete the whole work = 30 × (5/2) = 75 days
Therefore, time taken by 'Suresh' to complete 75% of the work = 0.75 × 75 = 56.25 days
