Answer 1

PLS MARK BRAINLIEST & ♥️⭐

Step-by-step explanation:

Let the cost of a pen and a pencil be x and y respectively.

4x+4y=100

x+y=25    ...(1)

3x=y+15

3x−y=15    ...(2)

Adding (1) and (2), we get

4x=40

x=10

Substitute x=10 in equation (1) to get y=15.

Answer 2

Answer:

it goes here ;)

Step-by-step explanation:

cost of 1122 pencil = 3340

cost of 1 pencil= 3340/1122

cost of 220 pencil= 3340/1122

= 33400/51

in mixed fraction = 65 25/51

hope it helps :)
