Directions (9-10) Answer the questions based on the information given below.

Given below is information about number of vivo phones, oppo phones and samsung phones sold by three shopkeepers namely Ashish, Amit and Ram. The ratio of number of vivo phones sold by Ashish and Amit is 5:2, respectively. The number of samsung phones sold by Ram is 250% more than the number of vivo phones sold by Amit.

The ratio of the number of samsung phones sold by Amit and Ram is 1:4, respectively. Sum of the number of vivo phones and samsung phones sold by Amit is equal to the difference between the number of vivo phones and oppo phones sold by Ashish. Number of oppo phones sold by Ram is twice the number of oppo phones sold by Ashish. Sum of number of vivo phones sold by Amit and the number of oppo phones sold by Ram is 1080.

Note:

a) The number of vivo, oppo and samsung sold by each person is not in fraction.

b) Each person sold vivo, oppo and samsung only in two variants i.e. Gaming and Flagship.

9. If the number of vivo phones (which are of gaming variants) sold by Ashish is equal to the number of oppo phones (which are of flagship variant) sold by him and number of vivo phones (which are of flagship variant) sold by him is five times the number of oppo phones (which are of gaming variant) sold by him, then find the number of oppo phones sold by Amit given the condition that number of oppo phones sold by him is 6 times the number of vivo phones (which are of gaming variant) sold by Ashish.

Common Solutions (1-3):

According to the question, Number of people who purchased cars in 2010 = (a + 800)

Number of males who purchased cars in 2010 = 0.2(a + 800) = (0.2a + 160)

Number of people who purchased cars till 2011 = 33b

Number of people who purchased cars till 2012 = 49b

Therefore, number of people who purchased cars in 2012 = 49b – 33b = 16b

According to the question,

0.90625 × 16b – 0.09375 × 16b = 2600

Or, 0.8125 × 16b = 2600

Or, 13b = 2600

Or, b = 200

Therefore, number of people who purchased cars in 2012 = 16b = 3200

Number of males who purchased cars in 2012 = 0.09375 × 3200 = 300

Number of females who purchased cars in 2012 = 3200 – 300 = 2900

Number of males who purchased cars in 2011 = 300 × 6 = 1800

Number of males who purchased cars till 2012 = 0.3 × 49b = 2940

Therefore, 0.2a + 160 + 300 + 1800 = 2940

Or, 0.2a = 680

Or, a = 3400

Therefore, number of people who purchased cars in 2010 = a + 800 = 4200

Number of males who purchased cars in 2010 = 0.2 × 4200 = 840

Number of females who purchased cars in 2010 = 4200 – 840 = 3360

Number of people who purchased cars in 2011 = 33b – 4200 = 6600 – 4200 = 2400

Number of males who purchased cars in 2011 = 1800

Number of females who purchased cars in 2011 = 2400 – 1800 = 600

Number of people who purchased cars till 2014 = a + 52.5b = 3400 + 52.5 × 200 = 13900

Number of males who purchased cars till 2014 = 0.4 × 13900 = 5560

Number of females who purchased cars till 2014 = 13900 – 5560 = 8340

Number of females who purchased cars in 2013 = 5.6 × 200 = 1120

Therefore, number of females who purchased cars till 2013 = 1120 + 3360 + 600 + 2900 = 7980

Number of females who purchased cars in 2014 = 8340 – 7980 = 360

Number of males who purchased cars in 2013 = 360 + 120 = 480

Number of people who purchased cars in 2013 = 480 + 1120 = 1600

Therefore, number of people who purchased cars in 2014 = 13900 – (1600 + 4200 + 2400 + 3200)

= 2500

Therefore, number of males who purchased cars in 2014 = 2500 – 360 = 2140

1. Desired ratio = 1800:360 = 5:1

2. Required number of females = 0.25 x (2900 + 1120) = 1005

3. Required average = (1800 + 300 + 480 + 2140)/4 = 1180

Common solution (3-8)

Let the number of male teachers and female teachers in school P be 5x and 3x respectively.

According to question,

=> 1.2 × 3x = 180

=> x = 50

Number of male teachers in school P = 5 × 50 = 250

Number of female teachers in school P = 3 × 50 = 150

Total number of teachers in school P = 250 + 150 = 400

Number of male teachers in school Q = 0.60 × 250 = 150

Total number of teachers in school Q = 150 + 180 = 330

Total number of teachers in school R = 1.20 × 330 = 396

Number of female teachers in school R = (21/25) × 250 = 210

Number of male teachers in school R = 396 – 210 = 186

Number of male teachers in school S = 186 – 56 = 130

Number of female teachers in school S = 150 – 30 = 120

Total number of teachers in school S = 130 + 120 = 250

4. Total number of teachers in school S = 250

5. Required ratio = 180:186 = 30:31

6. Required difference = 400 – 250 = 150

7. Required average = (250 + 186)/2 = 436/2 = 218

8. Required % = [(150 – 120)/120] × 100 = 25%

Common solution (9-10)

Let the number of vivo phones sold by Ashish and Amit be ‘5x’ and ‘2x’,respectively

Therefore, number of samsung phones sold by Ram = 3.5 × 2x = 7x

Number of samsung phones sold by Amit = 7x/4 = 1.75x

Sum of number of vivo phones and samsung phones sold by Amit = 2x + 1.75x = 3.75x

Case 1:

Let the number of vivo phones sold by Ashish is more than the number of oppo phones sold by him.

So, 5x – (number of oppo phones sold by Ashish) = 3.75x

Or, number of oppo phones sold by Ashish = 5x – 3.75x = 1.25x

Number of oppo phones sold by Ram = 1.25x × 2 = 2.5x

=> 2.5x + 2x = 1080

=> 4.5x = 1080

=> x = 1080/4.5 = 240 (possible)

Case 2:

Let the number of oppo phones sold by Ashish is more than number of vivo phones sold by him.

So, (number of oppo phones sold by Ashish) – 5x = 3.75x

=> number of oppo phones sold by Ashish = 5x + 3.75x = 8.75x

Number of oppo phones sold by Ram = 8.75x × 2 = 17.5x

=> 17.5x + 2x = 1080

=> 19.5x = 1080

=> x = 1080/19.5 ~ 55.38 (not possible because number of oppo phones/vivo phones/samsung phones sold cannot be in decimals)

Therefore, x = 240

Number of vivo phones sold by Ashish = 5x = 1200

Number of vivo phones sold by Amit = 2x = 480

Number of oppo phones sold by Ashish = 1.25x = 300

Number of samsung phones sold by Amit = 1.75x = 420

Number of oppo phones sold by Ram = 2.5x = 600

Number of samsung phones sold by Ram = 7x = 1680

Therefore,

9. Let the number of vivo phones sold by Ashish (which are of gaming variant) = number of oppo phones sold by him (which are of flagship variant) = y

Therefore, 1200 – y = 5 × (300 – y)

=> 1200 – y = 1500 – 5y

=> 4y = 300

=> y = 75

Therefore, number of oppo sold by Amit = 6 × 75 = 450

10. Number of vivo phones sold by Ram = 1.5 × 480 = 720

Number of vivo phones sold by Ram (which are of flagship variant) = 720 – 240 = 480

Required ratio = 480:600 = 4:5
