 Q. Common Information Question: 1/3 The maximum number of cars of brand B-star sold in the Gurgaon region can be:
 ✖ A. 400 ✔ B. 450 ✖ C. 466 ✖ D. 360

Solution:
Option(B) is correct

Percentage contribution of Indore region is 16.67%, when the sales of Surat region is also included. If the sales of Surat is $x\%$ of the other four regions combined, then,

$=\dfrac{20.83}{(100+x)})×100$

$=16.67\%$

$⇒ x = 25$

⇒ Percentage contribution of Surat:

$= \dfrac{25}{125}×100$

$=20$

⇒ Actual percentage contribution of Vijaywada region:

$= \dfrac{16.67}{125}×100$

$= 13.33$

⇒ Actual percentage contribution of Valeno:

$= \dfrac{13.33}{2}$

$= 6.67$

⇒ Actual percentage contribution of B-star to the total sales:

$= \dfrac{33.29}{106.67}×100$

$= 31.19$

⇒ Actual Contribution of Gurgaon to the total sales:

$= \dfrac{37.5}{125}×100$

$= 30\%$

‘Total sales’ volume of Gurgaon can be from the sales of brand B-star alone which is equal to 30 % of 1500 = 450 cars.
