Amit bought 12 register for Rs 156 find the cost of 8 register.

Answer»

similarly,. 156×8

=1,248

=1248

= 104 ans.

sequence will be the same.

Let the cost of 8 registers be Rs.x

Register	12	8
Cost ( in Rs. )	156	x

If he buys less number of registers, the cost will also be less.

∴ It is a direct variation.

⇒ 12:8=156:x

\(⇒8/12=x/156\)

x= 8/12 x156

x= 104

∴ The cost of 8 such registers will be Rs.104

12 --------------> 156

8 -----------------> X

X = 156*8/12

X= 104
