Question

Rabi has ₹ 4900 in his wallet in denominations of ₹ 200 and ₹ 500. If he has equal number of ₹ 200 and ₹ 500 notes, then how many notes are there in total?

• A. 7
• B. 5
• C. 14
• D. 9

Answer 1

The correct option is C 14

$\text{Let the number of each type of}\text{notes be}x\text{.}$

$\text{Total value of ₹ 200 notes}=200x$
$\text{Total value of ₹ 500 notes}=500x$

$\text{Total amount in the wallet}=200x+500x,\text{which is equal to 4900.}$

$\Rightarrow 200x+500x=4900\Rightarrow 700x=4900\Rightarrow x=\frac{4900}{700}\Rightarrow x=7$

$\text{Therefore, total number of notes}\text{in the wallet is 7+7=14.}$
