11. Calculate quantity I and Quantity II on the basis of the given information then compare them and answer the following questions accordingly.

Quantity I: A boat can travel ‘x’ km upstream in 4 hours and ‘y’ km downstream in 3 hours. If the speed of boat in still water is 5 km/h and the boat can travel a distance of ‘x+y’ km downstream in 4 hours, then find the speed of stream (in kmph)?
Quantity II: If time taken to cover (D+11) km upstream is thrice the time taken to cover (D–3) km downstream. If ratio of speed of boat in upstream to the downstream is 3 : 7 and time taken to cover (D+18) km downstream is 2.5 hours what will be the speed of current (in kmph)?
1. Quantity I > Quantity II
2. Quantity I < Quantity II
3. Quantity I ≥ Quantity II
4. Quantity I ≤ Quantity II
5. Quantity I = Quantity II

Option “2” is correct
12. Calculate quantity I and Quantity II on the basis of the given information then compare them and answer the following questions accordingly.

Quantity I: The respective ratio between the present ages of son, mother, father and grandfather is 2 : 7 : 8 : 12. The average age of son and mother is 27 yr. What will be mother’s age after 7 yr?
Quantity II: The age of the father 5 years ago was 5 times the age of his son. At present the father’s age is 3 times that of his son. What is the present age of the father?
1. Quantity I > Quantity II
2. Quantity I < Quantity II
3. Quantity I ≥ Quantity II
4. Quantity I ≤ Quantity II
5. Quantity I = Quantity II

Option “1” is correct
13. Calculate quantity I and Quantity II on the basis of the given information then compare them and answer the following questions accordingly.

Quantity I: C’s share (in Rs), if Rs. 3000 distributed among A, B and C such that A gets 2/3 rd of what B and C together get and C gets 1/2 of what A and B together get
Quantity II: Aman’s share (in Rs), if Rs. 2250 is divided among three friends Aman, Bijoy and Chandra in such a way that 1/6 th of Aman’s share, 1/4 thof Bijoy’s share and 2/5 th of Chandra’s share are equal.
1. Quantity I > Quantity II
2. Quantity I < Quantity II
3. Quantity I ≥ Quantity II
4. Quantity I ≤ Quantity II
5. Quantity I = Quantity II or No relation

Option “2” is correct
14. Calculate quantity I and Quantity II on the basis of the given information then compare them and answer the following questions accordingly.

A boat sails down the river for 10 km and then up the river for 6 km. The speed of the river is 1 km/hr.
Quantity I: Speed of boat in still water (in kmph), if for the whole trip it takes 4 hours.
Quantity II: 4 km/hr
1. Quantity I > Quantity II
2. Quantity I < Quantity II
3. Quantity I ≥ Quantity II
4. Quantity I ≤ Quantity II
5. Quantity I = Quantity II or No relation

Option “5” is correct
