Answer 1

Step-by-step explanation:

if, the pen price is=x

then the book's price is =(x+4)

and the pencil's price is=(x-2)

thus,

{(x+4)*5}+x*2+{(x-2)*3}=74

or,5x+20+2x+3x-6=74

or,10x+14=74

or,10x=74-14

or,10x=60

or,x=60/10

or,x=6

then,the book's price is 6+4=10

and the pencil's price is 6-2=4

and the pen's price is 6

Answer 2

Answer: price of pen= Rs 6, book= Rs 10

Pencil=4

Step-by-step explanation

Let the price of pen be P

Price of book= P+4

Price of pencil=P-2

5 books+2 pens+3 pencils=74

5(P+4) +2P+ 3(P-2) =74

5P+20+2P+3P-6=74

10P+14=74

10P=60

P=6

P is the price of the pen

Pencil=P-2= Rs 4

Book= P+4= Rs 10
