Un halterofil facand e antrenamente ridica zilnik ch 10kg mai mul de cannnd in ziua precedenta stind. Ca in 4 zile consecutive a ridicat 544 kg afla cate kg ridica halterofilul in fiecare din cele 4 zile

Answer 1

/__________/ = cat a ridicat in prima zi
/__________/___/ = cat a ridicat in a doua zi = prima zi+10
/__________/___/___/ = cat a ridicat in a treia zi = prima zi+20
/__________/___/___/___/ = cat a ridicat in a patra zi = prima zi + 30
In total, a ridicat 544 kg.
Se observa ca in total a ridicat de 4 ori cat a ridicat in prima zi + 10 + 20 +30 = de 4 ori cat a ridicat in prima zi + 60 kg = 544 kg
Atunci de 4 ori cat a ridicat in prima zi = 544-60 = 484 kg
Cat a ridicat in prima zi = 484:4 = 121 kg
In a doua zi aridicat 121+10 = 131 kg
In a treia zi a ridicat 131+10 = 141 kg
In a patra zi a ridicat 141+10 = 151 kg
