In the year 2000, the luxury car industry had two
car manufacturers Maruti and Honda with market
shares of 25% and 75% respectively. In 2001, the
overall market for the product increased by 50%
and a new player BMW also entered the market and
captured 15% of the market share. If we know that
the market share of Maruti increased to 50% in the
second year, the share of Honda in that year was:
ans. 35%
why we havn't considered the production increment by 50%

Let the total production in the year 2000 be '1000'
Maruti = 250
Honda = 750
It is mentioned, in 2001 production increased by 50%.
Total production in 2001 = 1500
BMW = 0.15*1500 = 225
Maruti = 0.5*1500 = 750
Honda = 1500 - 750 - 225 = 525
Honda % = 525/1500 * 100 = 35%
Hope this helps!

Exactly i thought that too , why they aren't considering that 50% hike , which should make 100(in 2000) to 150(in 2001) and ,then shares should be divided as 15% for BMW, 50% increase for Maruti makes shares chnge from 25% to 37.5% and rest goes to Honda that is 97.50% and then we should find comparison btw shares of Honda from 2000 that is 75% to 97.5% so it should be an increment of 30% . Can Any one tell wether i am right or wrong ??
