Mr Aaron Jude
Mr. Aaron Jude, a car dealer, sold cars of only two brands, A and B, in the previous year. This year,
he introduced a new brand, C. The number of cars of cars of brand A and brand B sold in the
previous year were in the ratio 3:2, and the ratio of the number of cars sold in the previous year to
that sold in this year is 2:3 for brand A and 2 : 5 for brand B. Further, the number of cars of brand C
sold this year forms 81 % of the total number of cars sold this year.
Q3: In the next year, Mr. Aaron Jude wants to increase the total sales by 80%, compared to the total
sales this year, by keeping the sales of each of A, B and C at the same level as that in this year and
introducing a new brand D. By what percent will the number of cars of brand D (to be sold next
year) be more than the total number of cars sold last year?

Answer:
total number of cars sold will be 900%
ans : 900%
Given : The number of cars of cars of brand A and brand B sold in the
previous year were in the ratio 3:2,
the ratio of the number of cars sold in the previous year to that sold in this year is 2:3 for brand A and 2 : 5 for brand B
number of cars of brand C sold this year forms 81 % of the total number of cars sold this year.
In the next year, Mr. Aaron Jude wants to increase the total sales by 80%, compared to the total sales this year, by keeping the sales of each of A, B and C at the same level as that in this year and introducing a new brand D
To Find : By what percent will the number of cars of brand D (to be sold next year) be more than the total number of cars sold last year?
Solution:
in the previous year
Car A sold = 6x then Car B Sold = 4x as ratio is 3: 2
Total car Sold = 10x
in this year car A sold (3/2)6x = 9x
in this year car B sold (5/2)4= 10x
Car A + Car B = 19x
cars of brand C sold this year forms 81 % of the total number of cars sold this year.
Hence 81x car C sold and total = 100x sold this year
Mr. Aaron Jude wants to increase the total sales by 80%, compared to the total sales this year,
Hence sales in next year = 100x + (80/100)100x = 180x
Brand D cars = 180x - 100x = 80x sold in next year
Cars sold in previous year = 10x
Car D sold in next year = 80x
80x - 10x = 70x
(70x/10x) * 100 = 700 %
700 percent will the number of cars of brand D (to be sold next
year) be more than the total number of cars sold last year
