a) 33 % less

b) 33 % more

c) 21 % more

d) 21 % less

e) 12 % more

The share of A, B and C,

= > [15000*4 + 20000*8] : [20000*4 + 17000*8] : [25000*9 + 30000*3]

= > [60000 + 160000] : [80000 + 136000] : [225000 + 90000]

= >220000 : 216000 : 315000

= >220 : 216 : 315

The share of C = 78750

315’s = 78750

1’s = 250

Total profit = 751’s = Rs. 187750

The ratio between the length and breadth of the rectangle = 8 : 5 (8x, 5x)

8x * 5x = 1000

40x2 = 1000

x2 = 25

x = 5

The side of the square = 8x – 16 = 40 – 16 = 24 cm

The area of the square = a2 = 242 = 576

The sum of 5 consecutive odd numbers = 125

Average of 5 consecutive odd numbers = 125/5 = 25

The average of consecutive number/odd/even number is always the middle number. So, the 5 consecutive odd numbers,

= > 21, 23, 25, 27, 29

The lowest even number = 3*25 + 3 = 75 + 3 = 78

The 7 consecutive even numbers,

= >78, 80, 82, 84, 86, 88, 90

Required ratio = 27 : 90 = 3 : 10

Let the sum be x and the rate of interest be r %,

According to the question,

[x*5*(r+6)]/100 – (x*5*r)/100 = 7500

(5xr + 30x)/100 – 5xr/100 = 7500

30x/100 = 7500

x = 7500*(100/30)

x = 25000

Sum (x) = Rs. 25000

Total probability = 15C3

Required probability = 1 – P (None is yellow)

Probability of getting none is yellow marbles,

= > 9C3 / 15C3 = 12/65

Required probability = 1 – (12/65) = 53/65

Directions (6-10):

The total number of pizzas sold by all the given stores in the month of July

= >6600 + 5000 + 5600 = 17200

The total number of pizzas sold by all the given stores in the month of November

= >7200 + 5600 + 6800 = 19600

Required ratio = 17200 : 19600 = 43 : 49

The total number of pizzas sold in the month of January 2019 and August 2018 together

= >5600*(120/100) + 6200*(125/100) + 7400*(110/100) + 5200 + 4600 + 5400

= >6720 + 7750 + 8140 + 5200 + 4600 + 5400

= > 37810

The average number of pizzas sold by store P in all the given months together

= >(6600 + 5200 + 6000 + 4800 + 7200 + 5600)/6

= > 35400/6 = 5900

The total number of pizzas sold by store Q in all the given months together

= >5000 + 4600 + 6400 + 5000 + 5600 + 6200

= > 32800

The total number of pizzas sold by store R in all the given months together

= >5600 + 5400 + 5800 + 5200 + 6800 + 7400

= > 36200

Required difference = 36200 – 32800 = 3400

Total number of pizzas sold by all the given stores in the month of September

= >6000 + 6400 + 5800 = 18200

Total number of pizzas sold by all the given stores in the month of October

= >4800 + 5000 + 5200 = 15000

Required % =[(18200 – 15000)/15000]*100 = 21.33 % = 21 % more
