Question

Weight of M,D and I is 74.Sum of D and I is 46 greater than M.I is 60% lessthan D.what is D weight; Weight of M,D and I is 74.Sum of D and I is 46 greater than M.I is 60% lessthan D.what is D weight

Answer 1

•M+D+I=74

•D+I=M+46

•I=(60/100)×D

THEREFORE, D+I=M+46

:D+[(3/5)×D]=M+46

:(5D+3D)/5)-46=M

:M=(8D/5)-46

THEREFORE, M+D+I=74

:[(8D/5)-46]+D+[(3D/5)]=74

:(8D+5D+3D)/5=74+46

:16D=120×5

:D=600/16

:D=37.5
