Answer 1

Answer:

reducing the price of CFL by 10% will cost equal to that of bulb.

Explanation-

In 100rs a CFL works for 2.5 years = 30 months

In 15rs a bulb works for 5 months or we say that 6 bulbs will work for 30 months with cost of 90 rs. so for same working period say 30 months the CFL costs 100rs and the bulb costs 90rs so by reducing the price of CFL by 10% it will cost only 90 rs same as bulb costs.

Answer 2

Answer:

answer is 10%

Step-by-step explanation:

as we know well that price of a regular bulb =₹15

one CFL bulb will work up-to 30 months.(₹100)

so, 6 regular bulbs will work up-to same period of 30 months. (₹90)

difference between prices of two products is ₹10

then, 10/100 of 100=10%

hope it helps you.......
