Total amount= 200+ 220= 420 rs

Answer 2

Answer :

$\large \underline{\boxed{\textsf{Total Amount = 420rs}}}$

Step-by-step explanation

$\underline{\underline{\textbf{Given that...}}}$

Vicky brought 2 1/2 kg apples and nitin bought 1 1/4kg apples cost 80rs per kg. And now we need to the total amount that they need to pay.

$\underline{\underlins{\textbf{Solution...}}}$

Here ,

$\mathsf{Total \:apples \: brought \:by \:Vicky\: = 2 \! \dfrac{1}{2} \, kg}$

$\mathsf{Total \:apples \: brought \:by \: Nitin \: = \dfrac{11}{4}kg}$

Now , Cost of 1kg apples = 80rs

Therefore

$\mathsf{Total\: amount \: Vicky \: have \: to \: pay\: = 2 \! \dfrac{1}{2} \times 80rs}$

For simplicity converting 2 1/2 to improper fraction we have

$\mathsf{2 1/2 = \dfrac{2 \times 2 + 1}{2} = \dfrac{5}{2}}$

Thus we have

$\mathsf{Total\: amount \: Vicky \: have \: to \: pay\: = \dfrac{5}{2} \times 80rs}$

$\implies \bold{\mathsf{ 200rs}}$

Now

$\mathsf{Total\: amount \: Nitin \: have \: to \: pay\: = \dfrac{11}{4} \times 80rs }$

$\implies \bold{\mathsf{ 220rs}}$

Therefore Now

$\mathsf{Total\: amount \: Both\: have \: to \: pay\: = 200rs + 220rs = 420rs}$

$\underline{\textbf{The required answer is :}}$

$\large \boxed{\underline{\mathsf{420rs}}}$
