Question

O persoana cheltuie 26% din suma pe care o avea si inca 440 lei. Stiind ca astfel ii mai ramane 30% din suma initiala, aflati aceasta suma.

Answer 1

x=suma initiala
26%x=26x/100
26x/100+440+30x/100=x
26x+44000+30x=100x
44x=44000
x=1000 lei suma initiala

Answer 2

x- (26x/100 +440)=30/100
100x-26x- 44000= 30
74x-30x=44000
44x=44000  |÷44
x=1000 lei
