Question

9.There is 15L soup in a pot. Surbhi serves 400mL in each bowl. If she fills 28 bowls, how much soup is left in the pot

​

Answer 1

GivEn:

• Amount of soup in a pot = 15 L

• Amount of soup served by Surbhi in each bowl = 400 mL

• Number of bowls filled by Surbhi = 28 bowls

⠀⠀⠀⠀⠀⠀⠀

To find:

• How much soup is left in the pot?

⠀⠀⠀⠀⠀⠀⠀

SoluTion:

⠀⠀⠀⠀⠀⠀⠀

${\underline{\bf{\bigstar\; According\;to\; Question\;:}}}$

⠀⠀⠀⠀⠀⠀⠀

Amount of soup served by Surbhi in 1 bowl = 400 mL

⠀⠀⠀⠀⠀⠀⠀

Amount of soup served by Surbhi in 28 bowls = 28 × 400 = 11,200 mL

━━━━━━━━━━━━━━━

⠀⠀⠀⠀⠀⠀⠀

Amount of soup in a pot = $\sf 15\;litres\;\;\;\;\;\;\;\;\;\bigg\lgroup\bf 1\;litre = 1000\;ml\bigg\rgroup$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 15 \times 1000$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\bf{\purple{15,000\;ml}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

Therefore,

⠀⠀⠀⠀⠀⠀⠀

Amount of soup left in a pot = 15,000 - 11,200 = 38,00 ml

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 38,00\;ml = 3800 \times \dfrac{1}{1000}\;\;\;\;\;\;\;\;\;\bigg\lgroup\bf 1\;ml = \dfrac{1}{1000}\;litre\bigg\rgroup$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 38 \cancel{00} \times \dfrac{1}{10 \cancel{00}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\bf{\pink{3.8\;litres}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore$ Hence, 3.8 litres soup left in the pot.
