10) A worker reaches his factory 3 minutes late of his speed from his house to the factory is 5 kmph. If he walks at a speed of 6 kmph, he reaches the factory 7 minutes early. The distance of the factory from his house is:

a) 3 km

b) 4 km

c) 5 km

d) 6 km

11) A man covers 12 km upstream and 18 km downstream in 3 hours, while he covers 36 km upstream and 24 km downstream in 6.5 hours. What is the speed of the current (in kmph):

a) 1

b) 1.5

c) 2

d) 2.5

12) The ratio of speed of a boat to that of the current of water is 36 : 5. The boat goes along with the current in 5 hours 10 minutes. It will come back in:

a) 5 hrs 20 min

b) 6 hrs 10 min

c) 6 hrs 50 min

d) 7 hrs 10 min

13) AB is a chord of a circle of radius 14 cm. The chord subtends a right angle at the centre of the circle. Find the area of the minor segment.

a) 98 sq cm

b) 56 sq cm

c) 112 sq cm

d) None of these

14) A cone and a hemisphere have equal bases and equal volumes. Find the ratio of their heights.

a) 1 : 2

b) 2 : 1

c) 3 : 1

d) None of these

15) Find the area of the quadrilateral ABCD. (Given, √3 = 1.73) a) 452 sq units

b) 269 sq units

c) 134.5 sq units

d) 1445 g cm Interest for first year = 5% of 20000 = Rs. 1000

Interest for second year = 5% of 21000 = Rs. 1050

Interest for third year = 5% of 22050 = Rs. 1102.50

Thus, the total interest earned in 3 yrs = 1000 + 1050 + 1102.50 = Rs. 3152.50.  or 2x + 2y = 3x – 3y

or x = 5y

or x : y = 5 : 1

Let x = 5k and y = k

(x2 – yb) : (x2 + yb) = (25 k2 – kb) : (25k2 + kb)

= 24 k2 : 26 k2 = 12 : 13.

Let the number of Re. 1, 50-paise, 25 paisa coins are x, 2x, 4x.

Total value of all the coins = 1×x + 0.50×2x + 0.25×4x = 3x

or 3x = 30.

Thus, x = 10.      Let the speed of the boat and of the current be 36v and 5v (in km per minutes), respectively.

Total distance covered by the boat in downstream = 41v  310 km

Let the boat takes t minutes to come back,

Then

41v × 310 = (36v –5v)t

t = 410 minutes = 6 hours 50 minutes Area of the sector ACBO =  90π × 142 / 30

= 154 sq cm

Area of the triangle AOB = (14 × 14) /2 = 98 sq cm

Area of the segment ACB = Area sector

ACBO – Area of the triangle AOB = 56 sq cm

Questions of this type should be solved without the use of pen and paper. A good authority over formulae will make things easier.

Volume of the cone = (πr2 h)/3 = volume of a hemisphere = 2 πr3 / 3

Height of a hemisphere = Radius of its base

So the question s effectively asking us to find out h/r

By the formula above we can easily see that h/r = 2/1.

Area of quadrilateral = Area of right angled triangle + Area of equilateral triangle ### *******************
