- The ages of five persons are 25.30.35.40.45
let the age of youngest person be "X".Then the age of remaining 4 persons will be X+5,X+10,X+15 and X+20.As each person donated 50 times their age and total donation was 8750,the required equation will be
50X+50(X+5)+50(X+10)+50(X+15)+50(X+20)=8750
50(5X+50)=8750
5X+50=175
5X=125
X=25 - 12 years agoHelpfull: Yes(2) No(1)
- let x be the age of 1st person then
50(50+5x)=8750
x=25
so ages of 5 persons are 25 30 35 40 45 respectively - 12 years agoHelpfull: Yes(1) No(1)
- let x be the age of first person,
age of second person be x+5,third person x+10,fourth person x+15,fifth person x+20.
it is given that,
50(x + x+5 + x+10 + x+15 + x+20) = 8750
x = 25,
thus ages are 25,35,45,55,65.
