A.1

B.2

C.3

D.4

E.0

(3/5) * (12/17) * 14025 – x + (48/100)*650 = 58

5940 – x + 312 = 58

6194 = x

(53/800)*9600 + ((1425/25)/3) = 127 + x

636 + 19 – 127 = x

X = 528

2717 ÷ [(22/100) * 650] = 35 × 5 3/7 of (17 ÷ x)

2717 ÷ 143 = 35 * (38/7)*(17/x)

19 = 35 * (38/7)*(17/x)

X = 35*(38/7)*(17)*(1/19)

X = 170

(56/100)*4250 + (36/100)*750 + (23/100)*x = 2788

2380 + 270 + (23/100)*x = 2788

(23/100)*x = 2788 – 2380 – 270

(23/100)*x = 138

X = 138*(100/23)

X = 600

Distance = speed * time

Length of train = x

Speed of train = y

x = y * 5/18 * 18

x = 5y

x + 250 = y * 5/18 * 36

x + 250 = 10y

5y + 250 = 10y

5y = 250

y = 50 kmph

Area of the rectangle = l * b

2x * x = 1440/5

X = 12 m

Length = 2 * 12 = 24 m

Difference = 24 – 12 = 12 cm

x * 120/100 * 125/100 * 115/100 = 1725000

x = 1000000

Required ratio = (7x * 40/100):(5x * 60/100)

= 14:15

B = 5 * 4/1 = 20 hours

4/x + 10/20 = 1

4/x = ½

1/x = 1/8

A + B = 1/20 + 1/8

= 7/40

Time = 40/7 hours = 5(5/7) hours

Given,

6c2/(x+18)c2=5/92

X2+35x-246=0

Simplify the above equation we get x=6

Required difference = 10-8=2 balls
