Directions (Q. 1-5):

(28/100)* 487.5 + (56/100)* 305.5 = 3 x

136.5 + 171.08 = 3x

3x = 307.58

X = 102.526

(3/4) * (187/513) * (14/21) * 1026 = x

X = 187

3 ½ + 5 7/8 – 6 ¼ + 4 ½ = x

(3+5-6+4) (½ + 7/8 -1/4 + 1/2) = x

X = 6((4 + 7 – 2 + 4)/ 8)

X = 6 13/8

X = 7 5/8

842 – 2176 ÷ 68 = 125x

7056 – 32 = 125x

7024 = 125x

X= 56.192

[56*56*8/ 28*28] ÷ 12 = 8x

32/12 = 8x

X = 32/ (8*12) = 1/3

Directions (Q. 6 – 10):

The pattern is, + (86*1), + (86*2), + (86*3), + (86*4)….

The pattern is, +(1*4), +(2*8),+(3*12), +(4*16)….

The pattern is, ÷ 2 + 1, ÷ 4 + 4, ÷ 6 + 7, ÷ 8 + 10….

The pattern is, *1 + 22, *2 + 32, *3 + 42, *4 + 52….

The difference of difference is, 7, 14, 21, 28….

Repairing cost percentage= 240*100/1200 = 20%

So he has to earn a profit of 20%

Total cost of the mobile= 1200+240= 1440

To earn 20% profit he should at= 1440*120/100= Rs 1728

Let the breadth of the rectangle be x

Length= x+10

So,

52= 2(x+x+10)

52= 4x+20

4x= 32

x= 8

Area of the rectangle= 8*18= 144

Side of the square= √144= 12

Perimeter of the square = 12*4= 48m

Total cost of mobiles A, B and C= 30000*3= Rs 90000

Average cost of A, B, C, D= 30000*80/100= Rs 24000

Total cost four mobile= 24000*4= Rs 96000

Cost of mobile D= 96000-90000= Rs 6000

According to the formula,

Quantity of milk left= 50(1- 10/50)2)

= 50* 4/5 * 4/5

= 32 litres

Let the present age of the man and his son be x and y respectively

So,

x – 5= 4(y-5) +3

x – 4y= -12….. (i)

Again

X+3 = 3(y+3) -6

x – 3y= 0…….(ii)

By solving, we get

X= 36, y=12

Sum of their ages = 48

Hence after 16 years the sum of their ages will be 80 years.

Directions (Q. 16 – 20)

Total number of students playing Carrom and Hockey together from school P = 220+140 = 360

Total number of students playing Carrom and Hockey together from School R = 200+320 = 520

Percentage = (360/520)*100 = 69 (3/13) %

Number of students in school S = 115% of 740 = 851

Number of students in school Q = 95% of 680 = 646

Difference = 851 – 646 = 205

Total number of students who got selected for state level competition from schools Q S and T

= 40% of 180 + 35% of 320 + 45% of 240

= 72 + 112 + 108 = 292

Total number of students playing Hockey from all the schools together = 140 + 260 + 320 + 160 + 180 = 1060

Total number of students playing Cricket from all the schools together = 360 + 180 + 240 + 320 + 240 = 1340

% = (1060/1340)*100 = 79 % (approximately)

Number of students who got selected for national level competition from School P = 25% of 40% of 220 = 22

Number of students who got selected for national level competition from School T = (2/3) of 45% of 280 = 84

Total number of students playing Carrom from these two schools who got selected for national level competition

= 22 + 84 =106
