M+D+I=74.D+I is 46 greater than M.I is 60% less than D.what is the weight of D?

• M+D+I=74 EQUESTION1
  D+I=M+46 EQUESTION 2
  I=D-D*60/100=.4D
  PUT THE D I VALUE IN EUESTION2
  1.4-46=M

• given M+D+I=74 and D+I=46+M
  so substitute D+I in first we get M=14,D+I=60
  given I is 60% lessthan D.
  60% in D is60/100D=3/5D
  60% less than D is=D-3/5D=2/5D
  therefore I=2/5D
  subsitute I value in D+I=60
  we get D=42.85=43
  so I=25.8

• D=50 (let)
  Hence, I=60% less Dan D; i.e. 20
  50+20=70; i.e.>M (whr M=4)
  Thus, D=50

• Ans: 10
  M + D + I = 74 ⇒ M = 74 -D - I
  M = D + I + 46
  I = 4D/10
  74-D-I=D+I+46
  74-D-4D/10=D=4D/10+46
  D=10Ans.
  74 - D - I = D + I + 46
  74 - D - 410 D = D + 410 D + 46
  ⇒ D = 10

  so

  D= 600/14

• From the very first statement we can see the value of D+I=46 as D+I is greater than M by 46.That means if we keep 46 in first equation M is obtained 28.Uptill now every condition is followed.Now calculating I:-
  I=D-60*D/100=40*D/100
  Now D+I=46
  So, D+40*D/100=46
  Thus,D=46*100/140=32.85
  Therefore value of D=32.85 or 230/7
