3 For each ornament that a worker makes, he is paid $3.35. He makes 5 ornaments
in every 20 minutes. Find the amount earned by the worker if he works for 4 hours.

Answer 1

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• For each ornament, a worker is paid $3.35.

• The worker makes 5 ornaments in every 20 min.

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}$

• Amount earned in 4 hours

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}$

• Ornaments made for every 20 min = 5

• Then, in 4 hrs = ?

First,

• Converting hrs to min,

• 1 hr $\longrightarrow$ 60 min

• 4 hr $\longrightarrow$ x min

Cross-multiplying,

• 1 * x = 60 * 4

• x = 240 min

Now,

• Ornaments made in 240 min = ?

• 5 ornaments $\longrightarrow$ 20 min

• x ornaments $\longrightarrow$ 240 min

Cross-multiplying,

• $\sf x \:* \:20\: = \:5 \:* \:240$

• $\sf 20x \:= \:1200$

• $\sf x \: = \: \dfrac{1200}{20}$

• $\sf x \: = \: \dfrac{120\cancel{0}}{2\cancel{0}}$

• $\sf x \: = \: \dfrac{\cancel{120}}{\cancel{2}}$

• x = 60 ornaments

Now,

• Amount earned for 60 ornaments =

• 1 ornament $\longrightarrow$ $3.35

• 60 ornaments $\longrightarrow$ $ x

Cross-multiplying,

• 1 * x = 60 * 3.35

• x = $201

Therefore,

• $\underline{\boxed{\purple{\tt{Amount \: earned \: by \: the \: worker \: in \: 4 \: hrs \: = \: \ 201.}}}}$

Answer 2

The Amount earned in 4 hrs is $ 201
