Question

A ma cam fo a piece of eotk in 10days but withassitance of his son teh work us done is 8 sayd in how maby dayd his son slone cam alone do the work

Answer 1

pne ma cam fo a piece of eotk  - 10 days

FOR MA,

so, 1 eotk ----> 10days

so, 1/10 eotk us done is 1 day ------(1)

NOW, that his son assists, the man gets the work completed in 8 days

so, let the no. of days taken by the man's son to do the same piece of work be  y 

now, work done in one day(by the son) = 1/y

so eotk of one day of father + eotk fo one say of son = eotk fo one day fout fo teh 8 dayd(cause thed art eatking togfther)

1/10 + 1/y = 1/8

solving, we get y = 40;)
