Question

Preeti purchased 4 t-shirts, 3 pants, 2 shirts, 2 saree and a pair of sandals. Cost of a t-shirt is Rs.500, cost of a pant is Rs.600. Saree and shirt cost Rs.600 each and pair of sandals cost Rs.500. What will Preeti have to pay for all the articles? Is it right to calculate the total amount as 500 x (4 + 1) + 600 (3 +2 +2) ? Give reason

Answer 1

$Given \: Cost \:of \:a\: t-shirt = Rs \:500$

$Cost \:of \:a\: pant = Rs \:600$

$Cost \:of \:Saree \:and \:Shirt = Rs \:600$

$Cost \:of \:each \:pair \:of \:sandals = Rs\:500$

$Total \: amount \: of \: Preeti \: purchased$

$= Cost \:of (4 \: t-shirts + 3 \:pants + 2 \:shirts$

$+ 2 \:sarees \:and \: pair \: of \: Sandals)$

$= 4 \times 500 + 3\times 600$

$+ 2\times 600 +2 \times 600 + 500$

$= 500( 4 +1 ) + 600( 3 + 2+2 )$

$= 500 \times 5 + 600 \times 7$

$= 2500 + 4200$

$= Rs \: 6700$

Therefore.,

$\red{ Calculate \: the \: total \: amount \:as }$

$\green {\: 500( 4 +1 ) + 600( 3 + 2+2 ) }$

$\green { \:is \: correct. }$
