Question

rajesh did 1/6 of the work on monday , 1/8 of the work on tuesday and 1/5 of the work on wednesday . how much to work on thursday to complete a remaining work?​

Answer 1

Answer:

first lets make them like to let it be a little easier

LCM of 6, 8, 5 is 120

$\frac{1 \times 20}{6 \times 20} = \frac{20}{120}$

$\frac{1 \times 15}{8 \times 15} = \frac{15}{120}$

$\frac{1 \times 24}{5 \times 24} = \frac{24}{120}$

total work :-

$\frac{120}{120}$

work done by her :-

$\frac{20 + 15 + 24}{120} = \frac{59}{120}$

work left for her to do :-

$\frac{120 - 59}{120} = \frac{61}{120}$

work left 61/120
