Question

the present cost of a mobile phone is ₹15000.If its value decreases every year by 5%,find its cost 2 year ago.

Answer 1

10÷100×15000

=₹1500

The cost of phone will be fifteen thousands

Answer 2

• CP = Rs. 15000
• Decrease % = 5 %

So its price after 2 years = 15000 x 95 % x 95 %

                                         = 15000 x 95/100 x 95/100

                                         = 13537.5
