Answer 2

❖ Question :

Find the value of 12% of 75 + 15% of 80.

ㅤ

❖ Answer :

First of all, we have to find 12% of 75. Then, we will find 15% of 80. Finally, we will add 12% of 75 and 15% of 80.

Let's do it!!

$\sf{↣ \: 12\% \: of \: 75}$

$\sf{↣ \: \dfrac{12}{ \cancel{100}_{ \: 4} } × \cancel{75}^{ \: 3} }$

$\sf{↣ \: \dfrac{ \cancel{12}^{ \: 3} }{ \cancel{4}_{ \: 1} } × 3}$

$\sf{↣ \: 9}$

Hence, 12% of 75 is 9.

$\sf{↬ \: 15\% \: of \: 80}$

$\sf{↬ \: \dfrac{ \cancel{15}^{ \: 3} }{ \cancel{100}_{ \: 20} } × 80}$

$\sf{↬ \: \dfrac{3}{ \cancel{20}_{ \: 1} } × \cancel{80}^{4} }$

$\sf{↬ \: 12}$

Hence, 15% of 80 is 12.

Now,

$\sf{⇢ \: 12\% \: of \: 75 + 15\% \: of \: 80}$

$\sf{⇢ \: 9 + 12}$

$\sf{⇢ \: 21}$

Hence, the value of 12% of 75 + 15% of 80 is 21.
