Question

at family reunion there were only blood relatives consisting of childrens parents and grandparents in attendance there for 400 people total there were twice as many parents as grandparents and 50 more children than parents.how many children parents and grandparents attendance​

Answer 1

let,grand parents =x,

so parents=2x and children=2x+50

ATQ,x+2x+2x+50=400

or,5x+50=400

or,5x=400-50

or,5x=350

or, x=350÷5=70

so,number of grand parents,x=70, parents,2x=70×2=140, children (2x+50),=140+50=190
