Important for :
1
What is the average number of cars sold (in thousand) by showroom C in all the given months together?
» Explain it
A

Reqd avg

 = 156 + 179 + 211 + 259 + 230 5

 = 1035 5

=   207 thousand

Hence, option A is correct.

2
By what percent the number of cars sold by showroom B increase from March to July?
» Explain it
B

Reqd %

 = 231 – 180 × 100 180
 = 51× 100 180

=   28.33%

Hence, option B is correct.

3
The number of cars sold by showroom E increased by 8% from July to August and by 20% from August to September. How many cars were sold (in thousand) by store E in September?
» Explain it
C
No. of cars sold by showroom E in July = 250

Now, as two percentage transactions are incurring on one specific base value we can apply the net % effect formula to get to know the overall % increase.

Net % effect = x + y + (xy)/100

Putting the values we get,

Net % effect = 8 + 20 + (8 x 20)/100 = 29.6%

Therefore, the number of cars sold by E in September = 129.6% of 250 = 324

Hence, option C is correct.

4
The total number of cars sold by all the given stores together in August was 7/9 of the total number of cars sold by all the given stores together in June. How many cars were sold (in thousand) by all the given stores together in August itself?

C

The number of cars sold by all stores in August

 = 7 of (Cars sold by all stores in June) 9

 = 7 × (205 + 198 + 259 + 165 + 181) 9

 = 7 × 1008 = 7 × 112 = 784 9

Hence, option C is correct.

5
The no. of cars sold by showroom D in July is approximately what percent more than the number of cars sold by show room A in March?
» Explain it
E

Reqd %

 = 178 – 154 × 100 154

 = 24 × 100 154

=   15.6%

Hence, option E is correct.
