Answer 1

Answer: Rs. 10 85 paise.

Step by step explanation:

Cost of pen: 15 2/3 = 47/3 = Rs. 15.60 ( approx. )

Cost of pencil: 4 3/4 = 19/4 = Rs. 4.75

Thus, Cost of pen is more.

Difference: 15.60 - 4.75 = 10.85

Thus, the cost of pen is more than that of pencil, by Rs. 10.85.

Answer 2

Answer:

₹ 10 11/12

Step-by-step explanation:

Cost of pen= ₹ 15 2/3= ₹ 47/3

Cost of pencil= ₹ 4 3/4= ₹ 19/4

₹ 15 2/3 > ₹ 4 3/4.

So, cost of pen is more.

Difference= ₹ 47/3 - ₹ 19/4

LCM of 3 and 4 is 12.

So, 47/3= 188/12

Similarly, 19/4= 57/12

Now, 188/12 - 57/12

= (188-57)/12

= ₹ 131/12 or ₹ 10 11/12
