Answer 1

$\sf\bold{\underline{Question:}}$

A tailor needs 1.25 m of fabric for one shirt and 2.5 m for one trousers. How much fabric does the tailor need to make 28 shirts and 20 trousers?

$\sf\bold{\underline{Given:}}$

$\sf{\mapsto Fabric\: needed \:for\: one \:shirt \:= \:1.25 \:m}$

$\sf{\mapsto Fabric \:needed \:for\: one \:trouser\: =\: 2.5 \:m}$

$\sf\bold{\underline{To\:find:}}$

$\sf{\mapsto Fabric\: needed \:for\: 28 \:shirts }$

$\sf{\mapsto Fabric \:needed \:for\: 20 \:trousers}$

$\sf\bold{\underline{Concept:}}$

${\underline{\sf{Total\:fabric\:needed\:=\:Fabric\:needed\:for\:one\:shirt \times \:Number \:of\:shirts\:given}}}$

$\sf\bold{\underline{Solution:}}$

$\sf{1. Fabric\:needed\:for\:28\:shirts}$

$\sf\longrightarrow {1.25}\times{28}=35\:m$

$\sf{1. Fabric\:needed\:for\:20\:trousers}$

$\sf\longrightarrow {2.5}\times{20}=50\:m$

$\sf\bold\green{\underline{Just\:to\:know\:more}}$

If it is given in the question that we have to find the cost of making fabric then we have to multiply the cost with total fabric.

$\underline{\sf Total\:cost\:=\:Cost\:of\:1\:m\:length \times \:Total\:Fabric}$
