Answer:
Price of pencil=2
Price of notebook=9
Price of pen = 16
Step-by-step explanation:
let the prize of pencil=a-d
let the prize of notebook = a
let the price of pen be = a+d
So , sum=27
or,a-d+a+a+d=27
or,3a=27
or,a=9
Now, (a-d)²+a²+(a+d)²=341
or,3a²+2d²=341
or,243+2d²=341
or,2d²=98
or,d=7
So,
16
sum=27
a-d+a+a+d=27
3a=27
a=9
(a-d)²+a²+(a+d)²=341
3a²+2d²=341
243+2d²=341
2d²=98
d=7
pencil=2
notebook=9
pen = 16
