Question

a watch and pen together cost rs 140. if cost of the watch be 6 times the cost of the pen,what is the cost watch?

Answer 1

Let cost of pen be x
Watch cost = 6x
Atq
6x +x = 140
7x =140
x=140/7
x=20

Price of pen is 20 rs
Price of watch is 6*20
=120

Answer 2

First let x is peb

then watch will be 6 x .... becUse 6 times more costly then pen


So now add both

X + 6x = 140

7x = 140

X will be
X = 140/ 7 = 20

Put value of x in pen and watch


Pen is x = 20

Watch is 6 times so 6x = 6 ×20 = 120
