Answer 2

Answer:

4.10 rupees

Step-by-step explanation:

3 ballpoint pen = $18\frac{3}{4}$ = $\frac{75}{4}$

1 ballpoint pen = $\frac{75}{12}$ = 6.25 rupees

------------------------

5 sketch pen = $51\frac{3}{4}$ = $\frac{207}{4}$

1 sketch pen = $\frac{207}{20}$ = 10.35 rupees

-------------------------

difference of 1 sketch pen and 1 ballpoint pen's cost = 10.35 - 6.25 = 4.10 rupees
