Question

Aflati suma numerelor a+b+c+d stiind ca: a=1/10 din b ; b=1/2 din c ; c=2/5 din d ; d=500

Answer 1

a+b+c+d=?
a=1/10 din b
b=1/2 din c
c=2/5 din d
d=500
c=(500:5)x2=100x2
c=200
b=200:2=100
b=100
a=(100:10)x1=10x1=10
a=10
r: 10+100+200+500=810

Answer 2

c=(500*5)x2=100x2
c=200
b=200*2
b=100
a=(100*10)x1=10x1
a=10
10+200+100+500=810
