Answer 1

$Given \: 7158 + 0.7 \times 540 + 12.5 \% \:of \:672 = \red{?} \times 15$

$\implies 7158 + \frac{7}{10} \times 540 + \frac{12.5}{100} \times 672 = \red{?} \times 15$

$\implies 7158 + 7 \times 54 + \frac{1}{8} \times 672 = \red{?} \times 15$

$\implies 7158 + 378 + 84 = \red{?} \times 15$

$\implies 7620= \red{?} \times 15$

$\implies \frac{7620}{15}= \red{?}$

$\implies 508 = \red{?}$

$Value \:of \: \red{ ? } \green { = 508}$

$Option \: \pink { ( d ) } \:is \: correct$
