7) If the ratio of the roots of the equation x2 โ2ax + b = 0 is equal to that of the roots x2 โ2x + d = 0, then

a) a2b = c2d

b) a2c = b2d

10) If the Government imposes the 25% corporate profit tax, then what will be the profit maximizing output?

a) 16.5

b) 16.125

c) 15

d) 22

LCM of 3, 5 and 11 = 165

Now on dividing 2266 by 165, we get

1440 = 165 * 8 + 120

Thus, the least value which should be added to 2266 to make it divisible by 5, 7 and 11 = 165 โ 120 = 45

The whole work = x days

Time taken by P = 10 days

Q = 12 days

R = 15 days

LCM of 10, 12, 15 = 60

Total work = 60 Unit

P can complete 60/10 = 6 units/ day

Q = 5 units/ day

R = 4 units/ day

Pโs (2x) + Qโs (x โ 3) + R (x) = 60

6 (2) + 5 (x – 3) + 4 (x) = 60

12 + 5x โ 15 + 4x = 60

9x โ 3 = 60

x = 63/9

x = 7 days

So, the whole work will be completed in 7 days.

Let the larger Diagonal of rhombus = a

Other diagonal = 70a/100 = 7a/10

Area of rhombus : Square of larger diagonal

ยฝ Larger diagonal * smaller Diagonal : (larger Diagonal)2

ยฝ * a * 7a/10 : a2

7a2 : 20a2

7: 20

Distance traveled by Bullet = 0.125 km = 125 m

Time taken = 5 sec

Speed = Distance / time = 125/ 5 = 25 mps * (18/5)

= 5*18 = 90 Kmph

Total Distance = 61 km

Total time = 9 hours

Relative Speed = 61/9 kmph

Speed of the boy travelled on Foot = 4 kmph

Speed of the boy travelled on bicycle = 9 kmph

On Alligation,

Time ratio of On foot and bicycle = 4x : 5x

ย Time taken of the boy travelled on foot =ย = 4 hours

Speed of the boy to travel on foot = 9 kmph

Total distance = Speed * time = 4 * 9 = 45 km

Since, speed of wind = 5 km/h

It is passing horizontally for the will be less than the speed of the wind and will be in the same ratio

If the ratio of roots is n : 1

Then, the product of roots = n2 : 1 = b : d

Sum of the roots = a : c will be in ratio = n : 1

b/d = a2/c2

a2d = c2b

Sum of number 1 to 100 = 100/2 (1 + 100)

= 50 * 101 = 5050

Number which are divisible by 3 from 1 to 100

5, 10, 15, โฆโฆโฆ., 100

Sn = 20/2 (5 + 100)

= 10 * 105 = 1050

Number which is divisible by 3 and 5 must be divisible by 3 5 = 15 that are 15, 30,………, 90

Sn = 6/2 (15/90)

= 3 * 105 = 315

Sum of number which is divisible by 3 and 5 are = 1050 + 1683 โ 315 = 2418

Sum of number which are not divisible by 3 and 5 = 5050 โ 2418 = 2632

(i) The demand for a product (Q) is related to the price (P) of the products as follows Q =100 โ 2P

(ii) The cost (C) of manufacturing the product is related to the quantity produced in the following manner C = (Q2 โ 16Q + 2000)

(iii) As of now the corporate profit tax rate is zero. But the government of India thinking of imposing 25% tax on the profit of the company.

Even after imposing tax on profit the profit maximizing output will still be 22.
