10) In a 3 km run, Pankaj beats kamal by 225 meters or 6 minute. Find the time taken by kamal to complete the race.

a) 86 minute

b) 78 minute

c) 76 minute

d) 80 minute

√q + (1/√q) = 7

Squaring both sides, we get

q + (1/q) + 2 × √q × (1/√q) = 49

q + (1/q) = 47

Again squaring both sides, we get

q+ (1/q2) + 2 × q × (1/q) = 2209

q2 + (1/q2) = 2207

Let boat’s speed = x km/ h

And speed of stream = y km/h

According to question,

X – y = 50/8 = 25/4   ……(i)

X + y = 50/5 = 10 ……..(ii)

On solving equations (i) and (ii)

x = 8.125

y = 1.875

Hence speed of the stream = 1.875 km/h

Decrease in value from previous year =20%

Last Year Computer Price= 32400×100/80=3240000/80=Rs.40500

Hence the value of computer last year= Rs.40500

Arranged in ascending order,

13, 24, 26, 29, 30, 33, 44

n = 7 (odd)

Median = ((n+1)/2)th term

= ((7+1)/2) th term = 4th term = 29 On bisecting the BC– ABC is a right angled triangle whose angle A is right angled. For the creation of two other right-angled triangles, the side BC will have to bisect.

Volume of hemisphere = 2/3 × π × r3

Radius of hemisphere = (6750/2)1/3 = 15 m

According to Question – (Quantity of A / Quantity of B) = 30/30

Ratio = 1:1

The ratio of profit = 12500: 13000: 10500

= > 25: 26: 21

A’s share = Rs. 4500

25’s = 4500

1’s = 180

B’s share =180*26 = Rs. 4680

Let Cost price =100

Selling price =100 + 25 = 125

According to Question-

On changing the value of the cost price and the selling price

Cost price = 125

Selling price = 100

Loss Percent = (125 – 100)/125 × 100

= 25/125 × 100 = 20%
