• C. $(₹2\times 5)+(₹2\times 7)$
• D. $(5+7+₹2)$

Answer 1

Answer: (A), (C)

$(₹2\times 5)+(₹2\times 7)$

$\text{Number of chocolates Ram bought}=5\text{Number of chocolates Sam bought}=7\text{Cost of each chocolate = ₹ 2}$

$\text{Cost of chocolates Ram bought}=₹2\times 5$
$\text{Cost of chocolates Sam bought}=₹2\times 7$

$\text{Total cost}=(₹2\times 5)+(₹2\times 7)=₹2\times (5+7)$
