Question

A and B together can do a piece of work in 15 days. If A's one day work is 1 1/2 the one day's work of B, find in how many days can each do the work​

Answer 1

$A+B=\frac{1}{15}$

$\: \: \: \: \: \: \: \: \: \: \frac{13}{2} B = \frac{1}{15}$

$\: \: \: \: \: \: \: \: \: \: B = \frac{2}{195}$

$∴A = \frac{1}{15} - \frac{2}{195}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: A = \frac{11}{195}$

$Hence,\: A \:can\: do\: a \:piece\: of\: work \:in\: \frac{11}{195}$

$days\: and B \: can \: do\:a\:piece\:of\:work\:in\: \frac{2}{195} \: days$
