Question

In a survey it was revealed that out of 720 people, 1/18th of them like pizzas, 1/12th of them like burgers,1/8th of them like momos and the rest like home food. How many people like home food?

Answer 1

Given

Total no: of people = 720

$\bold {=> No: \ of \ people \ who \ like \ pizzas}$

$= \frac{1}{18} *720$

$= 40 \ people$

$\bold {=> No : \ of \ people \ who \ like \ burgers}$

$= \frac{1}{12} * 720$

$= 60 \ people$

$\bold {=> No : \ of \ people \ who \ like \ momos}$

$= \frac{1}{8} * 720$

$= 90\ people$

Total No: of people who like home made food

= 720 - ( 40 + 60 + 90)

= 720 - 190

= 530

❏ Question:-

@ In a survey it was revealed that out of 720 people, 1/18th of them like pizzas, 1/12th of them like burgers,1/8th of them like momos and the rest like home food. How many people like home food?

❏ Solution:-

• Total No. of peoples = 720

• No. of peoples like pizzas ,

$\dfrac{1}{18}$'th 0f 720

$\longrightarrow \dfrac{1}{18}\times720$

$\longrightarrow \dfrac{1}{\cancel18}\times\cancel{720}$

$\longrightarrow 40$

• No. of peoples like burgers ,

$\dfrac{1}{12}$'th 0f 720

$\longrightarrow \dfrac{1}{12}\times720$

$\longrightarrow \dfrac{1}{\cancel{12}}\times\cancel{720}$

$\longrightarrow 60$

• No. of peoples like momos ,

$\dfrac{1}{8}$'th 0f 720

$\longrightarrow \dfrac{1}{8}\times720$

$\longrightarrow \dfrac{1}{\cancel{8}}\times\cancel{720}$

$\longrightarrow 90$

Now , according to the question the rest of the peoples like Home food ,

• No. of peoples like Home Food ,

$\longrightarrow 720-(40+60+90)$

$\longrightarrow 720-190$

$\longrightarrow \boxed{530}$

$\therefore$ No. of peoples like Home Food = 530
