Answer 1

Given...

The cost of radio during 1980was the rs.120.In the 1988, the prize had increased to rs. 180. ..


Change in Price from 1980 to 1988...


= Market Price in 1988 - Market Price in 1980

= 180 - 120..

=60 .. (Increase)


Then the percentage increase in the cost of radio

= (Change in cost /cost in earlier year)×100

=(increase in cost/cost in 1980)×100

=(60 /120)×100

=50%

So the percentage increase in the cost of the radio = 50%
