$let \: the \: total \: wrk \: = 1 \: part$

$in \: 24days \: a \: can \: do \: 1part \: work$

$in \: day \: a \: can \: do \: \frac{1}{24} part \: of \: the \: work$

$as \: b \: is \: 50\% \: more \: eficent \: than \: a \: so$

$in \: 1 \: day \: b \: can \: do \:$

${( \frac{1}{24} + ( \frac{1}{24})} \: \frac{50}{100} part \: of \: work \:$

= (2+1)/48 part of work = 1/16 part of work

☞Therefore, B can do 1/16 part of work in 1 day

☞Therefore B can do 1 part of work in 1*16/1 day

☞Therefore B can complete the work in 16 days.ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
