and Cost of a cheaper lamp costs Rs.85 pls verify

Answer 2

Answer:

Rs.115

Step-by-step explanation:

James bought 5 CFL of each kind

Cost of 1 piece of cheap CFL = Rs.85

Cost of 5 pieces of cheap CFL = $85 \times 5=425$

Let the price of 1 piece of costlier  CFL be x

Cost of 5 pieces of costlier  CFL = 5x

We are given that the total price of both kinds of CFL is Rs.1000

So, $425+5x=1000$

$425+5x=1000$

$5x=1000-425$

$x=\frac{1000-425}{5}$

$x=115$

Hence the price of one of the costlier kind is Rs.115
