10% of a money is Rs 40, Find 30% of it.

${\large{\mathfrak{\fbox{\pink{Solution :→}}}}}$

Let's take the amount be x

Therefore,

${\bold{\sf{ \: \: \: \: \: \: \: \: \: \: : \: ⟹ \: \: \: \: \: 10 \: \% \: of \: x \: = \: Rs. \: 40}}}$

${\bold{\sf{ \: \: \: \: \: \: \: \: \: \: : \: ⟹ \: \: \: \: \: \frac{10x}{100} = 40}}}$

Let's find the value of x

${\bold{\sf{ \: \: \: \: \: \: \: \: \: : \: ⟹ \: \: \: \: \: x \: \: = \: \: \frac{100}{10} × 40}}}$

${\bold{\sf{ \: \: \: \: \: \: \: \: \: \: : \: ⟹ \: \: \: \: \: x \: = \: 400}}}$

It means the amount is Rs. 400

➠ Now we have to calculate 30% of 400

${\bold{\sf{ \: \: \: \: \: \: \: \: \: \: : \: ⟹ \: \: \: \: \: \frac{30}{100} × 400}}}$

${\bold{\sf{ \: \: \: \: \: \: \: \: \: \: : \: ⟹ \: \: \: \: \: 120}}}$
