​

Answer 1

• $\huge\pink{\mid{\fbox{\tt(answer)}\mid}}$
• $30 \times 4500 \div 750 = 30 \times 6 \\ \\ = 180$

Answer 2

Given thαt,

• A mαchine prints 750 pαges in 30 minutes.

❍ We need to find the time tαken by mαchine to print 4500 pαges.

_________

To do so,

firstly let's have a look on what's given,

Time tαken by mαchine to print 750 pαges = 30 min

So, Time tαken by the mαchine to print 1 page = $\displaystyle{\sf{ \dfrac{30}{750}}}$

And Time tαken to print 4500 pages = $\displaystyle{\sf{ 4500 \times \dfrac{30}{750}}}$

• Simplify this

:$\implies{\sf{ 4500 \times \dfrac{30}{750}}}$

:$\large\implies{\boxed{\sf{\red{180}}}}$

• We can also write 180 mins as 3 hours.

Hence, Time tαken by the machine to print 4500 pαges is 3 hours or 180 minutes.
