Question

₹ 80 = x notes of ₹ 20
₹ 80 = y notes of ₹ 5
₹ 80 = z notes of ₹ 2

Which of the following are the values of x, y and z?

• A. x = 4, y = 16 and z = 40
• B. x = 4, y = 10 and z = 40
• C. x = 8, y = 16 and z = 10
• D. x = 4, y = 6 and z = 4

Answer 1

The correct option is A

x = 4, y = 16 and z = 40

$₹80=x\text{notes of ₹ 20}$
$\Rightarrow x=\frac{₹80}{₹20}=4$

$₹80=y\text{notes of ₹ 5}$
$\Rightarrow y=\frac{₹80}{₹5}=16$

$₹80=z\text{notes of ₹ 2}$
$\Rightarrow z=\frac{₹80}{₹2}=40$

$\therefore x=4,y=16\text{and}z=40$
