Question

If 5 pens cost ₹ 10 and 2 pencils cost ₹ 4, then the cost of 2 pens and 5 pencils are

• A. ₹ 16
• B. ₹ 12
• C. ₹ 10
• D. ₹ 14

Answer 1

The correct option is D ₹ 14

Cost of 5 pens = ₹ 10
$\Rightarrow$ Cost of 1 pen = $\frac{10}{5}=₹2$
Also, Cost of 2 pencils = ₹ 4
$\Rightarrow$ Cost of 1 pencil = $\frac{4}{2}=₹2$
$\therefore$
2 pens and 5 pencils cost : $2\times 2$ + $5\times 2$ = 4 + 10 = ₹ 14
