- Directions (Q.3-4): Cities M and N are 600 km apart. Bus A starts from city M towards N at 9 am and bus B starts from city N towards M at the same time. Bus A travels the first 1/3rd of the distance at a speed of 40 kmph, the second 1/3rd at 60 kmph and the third 1/3rd at 50 km/hr. Bus B travels the first 1/3rd of the total distance at a speed of 60 kmph, the second 1/3 rd at 40 kmph and the third 1/3rd at 50 km/hr.

3.

When and where will the two buses cross each other?

**Answer: Option 'C'**

**Bus A travels first 1/3 rd of the distance in 200/40 = 5 hrs
Bus B travels first 1/3 rd of the distance in = 200/60 = 10/3 hrs
in 5 - 10/3 = 5/3 hrs Bus B travels another 5/3 × 40 = 200/3 kms
Now, the distance between Buses A and B reduces 600 - (200 + 800/1) = 400/3 kms
This is covered by both in (400/1)/(60+40) = 1(1/3) hr
Hence, they will cross each other after = 5 + 1(1/3) = 6 hrs 20 minutes
And the point of crossing is 200 + 80 = 280 kms from city M **

4.

What are the approximately average speeds of Bus A and Bus B?

**Answer: Option 'A'**

**Average speed of bus A = 600/[(20/40)+(200/50)+(200/60)] = 48.64 km/hr
Average speed of bus B = 600/[(200/60)+(200/40)+(200/50)] = 48.64 km/hr **

- Directions (Q.5-6): According to a plan, a team of woodcutters decided to harvest 216 cubic meters of wheat in several days. In the first three days, the team fulfilled the daily assignment, and then it harvested 8 cubic metre of wheat over and above the plan every day. Therefore, a day before the planned date, they had already harvested 232 cubic meters of wheat.

5.

How many cubic metres of wheat a day did the team have to cut according to the plan?

**Answer: Option 'C'**

**Let, the planned no. of days be 'n' and planned harvest per day be 'x' m ^{3}
Then, nx = 216
ATQ, x(n-1) + 8(n-4) = 232
or, nx - x + 8n - 32 = 232
or, 8n - x = 48
or, 8n - 216/n = 48
or, 8n^{2} - 48n - 216 = 0
or, n^{2} - 6n - 27 = 0
=> (n-9)(n+3) = 0
=> n = 9
Hence, x = 216/9 = 24 m^{3}**

6.

To harvest 216 cubic metre of wheat 2 days before the planned date, how many cubic metres of wheat must be harvested by team over and the above the plan every day after first three days?

**Answer: Option 'B'**

**Amount of wheat harvested in first three days = 24 × 3 = 72 m ^{3}
Remained = 216 - 72 = 144 m^{3}
This has to be harvested in n - 3 - 2 = 4 days
Required Harvest per day = 144/4 = 36 m^{3}
Required additional harvest per day = 36 - 24 = 12 m^{3}**

7.

What is the probability of drawing at least one red ball?

**Answer: Option 'B'**

**The probability of at least one red ball = 1 - (probability of no red ball)
= 1 - (1/2) × (1/2) × (1/2) × (1/2)
= 1 - (1/16)
= 15/16 **

- Directions (Q.7-8): There are four boxes. Each box contains two balls. One red and one blue. You draw one ball from each of the four boxes.

8.

If each bag a green ball is added, then find the probability of drawing at least one blue ball?

**Answer: Option 'A'**

**The probability of at least one blue ball = 1 - (probability of no blue ball)
= 1 - (2/3) × (2/3) × (2/3) × (2/3)
= 1 - (16/81)
= 65/81**

Total runs given till last match = 12.4 × x
(12.4 × x)/(x+5) = 12
x = 85**

A and B started a business with the investments in the ratio of 5 : 3 respectively. After 6 months from the start of the business, C joined them and the respective ratio between the investments of B and C was 2 : 3. If the annual profit earned by them was Rs. 12300, what was the difference between B’s share and C’s share in the profit?

**Answer: Option 'A'**

**A : B = 5 : 3 = 10 : 6
B : C = 2 : 3 = 6 : 9
A : B : C = 10 : 6 : 9
Ratio for 1 month = (10x × 12) : (6x × 12) : (9x × 6) = 20 : 12 : 9
= 20 : 12 : 9
Required difference = (12 - 9)/41 = 12300 = 900 Rs.**
