GIVEN:

⊙ Cost of a pencil ✏️=₹14/5

⊙ Cost of an eraser is ₹27/10

TO FIND:

⊙ Total cost of a pencil and 2 erasers.

SOLUTION:

$\sf Cost \: of \: 1 \: eraser=₹ \dfrac{27}{10}$

$\sf Cost \: of \: 2 \: erasers =2× ₹ \dfrac{27}{10}$

$\sf Cost \: of \: 2 \: erasers =₹ \dfrac{54}{10}$

$\small \sf Cost \: of \: 2 \: erasers \: and \: 1 \: pencil=₹\dfrac{54}{10}+₹\dfrac{27}{10}$

$\small \sf Cost \: of \: 2 \: erasers \: and \: 1 \: pencil=₹\dfrac{54 + 27}{10}$

$\small \sf Cost \: of \: 2 \: erasers \: and \: 1 \: pencil=₹8.1$

Hence the total payment by Ryan for 2 erasers and 1 pencil is ₹8.1.
