A
Rs. 25

B
Rs. 50

C
Rs. 500

D
Rs. 100

A container has capacity of 20 litres and is full of milk. 10 Litre of milk is taken out of it and replaced by the same quantity of water again 10 litres of mixture is taken out and replaced by an equal quantity of water. How much milk is left in the mixture?

A
25 litres

B
5 litres

C
10 litres

15 litres

Solution

Given:

A container has capacity of 20 litres.

Here, the number of operations is 2 , that is n = 2

Milk left in the container after n operations/Original quantity of milk in the container.

Solution
Question 7
4 / -1

In a ΔABC, if a = 18, b = 24 and c = 30 then find the value of sin (A/2)?

A
1/√10

B
1/√5

C
1/√15

D
None of these

Solution

Given:

For ΔABC we have a = 18, b = 24 and c = 30

Here, we have to find the value of sin (A/2)

As we know that, if a, b and c are the sides of the Δ ABC then 2S = a + b + c

⇒ 2S = 18 + 24 + 30 = 72

⇒ S = 36

Question 9
4 / -1

A man walks from P to Q at the rate of 5 km/h and returns from Q to P at 3 km/h. What is his average speed for the whole journey?

A
3.25 km/h

B
3.75 km/h

C
3.5 km/h

D
8 km/h

Solution

Let the distance between P and Q be x km, then

As we know,

Average speed = Total distance/Total time
Question 10
4 / -1

Travelling at 3/4 of the normal speed, a person reaches his workplace 15 minutes late. How many minutes does he take usually to reach the workplace?

A
60 minutes

B
30 minutes

C
42 minutes

D
45 minutes

Solution

Let the normal speed be 4 km/hr

Travelling speed = 4 × (3/4) = 3 km/hr

Ratio of normal speed to travelling speed = 4x : 3x

As we know,

Time is inversely proportional to time.

Ratio of normal time to travelling time = 3x : 4x

4x – 3x = 15

⇒ x = 15

∴ Normal time = 3x = 3 × 15 = 45 min
