Question

$z + \frac{120}{100} z = 550 \\ ....help \: me \: plz$
​

Answer 1

$\huge\mathbb{SOLUTION:-}$

We have to find the Value of z in the Given equation

The equation is

$\sf:\bullet z+\dfrac{120}{100}z=550\\ \\ \sf:\:\:\:or\\ \\ \sf:\implies z+\dfrac{120z}{100}=550$

Now solve This

$\sf:\implies z+\dfrac{120z}{100}=550\\ \\ \sf:\implies By\: taking\:L.C.M\\ \\ \sf:\implies\dfrac{100z+120z}{100}=550\\ \\ \sf:\implies 220z=550\times 100\\ \\ \sf:\implies 220z=55000\\ \\ \sf:\implies z=\cancel{\dfrac{55000}{220}}\\ \\ \sf:\implies z=250$

$\boxed{\sf{z=250}}$
