Answer:
Step-by-step explanation:
Let x be the number plums that Mary had
Number of plums received by her brother = (1/4) of x =(1/4)x
Number of plums received by her sister = (1/3)x
Remaining plums is 20.
Total plums - (plums given to brother + plums given to sister) = 20
![x-(\frac{1}{4}x+\frac{1}{3}x)=20\\\\x-\frac{1}{4}x-\frac{1}{3}x=20\\\\\frac{1*12}{1*12}x-\frac{1*3}{4*3}x-\frac{1*4}{3*4}x=20\\\\\frac{12}{12}x-\frac{3}{12}x-\frac{4}{12}x=20\\\\\frac{12-3-4}{12}x=20\\\\\frac{5}{12}x=20\\\\x=20*\frac{12}{5}\\\\x=4*12\\\\x=48](https://tex.z-dn.net/?f=x-%28%5Cfrac%7B1%7D%7B4%7Dx%2B%5Cfrac%7B1%7D%7B3%7Dx%29%3D20%5C%5C%5C%5Cx-%5Cfrac%7B1%7D%7B4%7Dx-%5Cfrac%7B1%7D%7B3%7Dx%3D20%5C%5C%5C%5C%5Cfrac%7B1%2A12%7D%7B1%2A12%7Dx-%5Cfrac%7B1%2A3%7D%7B4%2A3%7Dx-%5Cfrac%7B1%2A4%7D%7B3%2A4%7Dx%3D20%5C%5C%5C%5C%5Cfrac%7B12%7D%7B12%7Dx-%5Cfrac%7B3%7D%7B12%7Dx-%5Cfrac%7B4%7D%7B12%7Dx%3D20%5C%5C%5C%5C%5Cfrac%7B12-3-4%7D%7B12%7Dx%3D20%5C%5C%5C%5C%5Cfrac%7B5%7D%7B12%7Dx%3D20%5C%5C%5C%5Cx%3D20%2A%5Cfrac%7B12%7D%7B5%7D%5C%5C%5C%5Cx%3D4%2A12%5C%5C%5C%5Cx%3D48)
Number of plums with Mary = 48
Number of plums received by brother= (1/4)*48 = 12 plums
Number of plums received by sister = (1/3)*48 = 16 plums
16 - 12 = 4
Her sister received 4 plums more than her brother
