Question

3. 15% of 260 + 16% of 225 +
12% of 275 = ?​

Answer 1

Required Answer :

$\sf {( 15 \% \: of \: 260) + (16 \% \: of \: 225) + (12 \% \: of 275) }$

Here, we can write the numbers in percentage in the form of 15/100 , 16/100 & 12/100.

$\sf { \longrightarrow \Bigg \lgroup \dfrac{15}{100} \times 260 \Bigg \rgroup + \Bigg \lgroup \dfrac{16}{100} \times 225 \Bigg \rgroup + \Bigg \lgroup \dfrac{12}{100} \times 275 \Bigg \rgroup }$

$\sf { \longrightarrow \Bigg \lgroup \dfrac{15}{10} \times 26 \Bigg \rgroup + \Bigg \lgroup \dfrac{8}{50} \times 225 \Bigg \rgroup + \Bigg \lgroup \dfrac{6}{50} \times 275 \Bigg \rgroup }$

$\sf { \longrightarrow \Bigg \lgroup \dfrac{3}{2} \times 26 \Bigg \rgroup + \Bigg \lgroup \dfrac{4}{25} \times 225 \Bigg \rgroup + \Bigg \lgroup \dfrac{3}{25} \times 275 \Bigg \rgroup }$

$\sf { \longrightarrow \Bigg \lgroup \dfrac{3 \times 26}{2} \Bigg \rgroup + \Bigg \lgroup 4 \times 9 \Bigg \rgroup + \Bigg \lgroup 3\times 11 \Bigg \rgroup }$

$\sf { \longrightarrow \Bigg \lgroup \dfrac{78}{2} \Bigg \rgroup + \Bigg \lgroup 4 \times 9 \Bigg \rgroup + \Bigg \lgroup 3\times 11 \Bigg \rgroup }$

$\sf { \longrightarrow \Big \lgroup 39 \Big \rgroup + \Big \lgroup 36 \Big \rgroup + \Big \lgroup 33 \Big \rgroup }$

$\sf { \longrightarrow \Big \lgroup 39 + 36 + 33 \Big \rgroup }$

$\sf \red{ \longrightarrow 108 }$

Hence, value of $\sf {( 15 \% \: of \: 260) + (16 \% \: of \: 225) + (12 \% \: of 275) }$ is 108.
