14. A, B and C enter into a partnership and their shares are in the ratio 1/2 : 1/3 : 1/4. After 2 months, A withdraws half of his capital and after 10 months, a profit of Rs. 378 is divided among them. What is B's share ?
Answer: 144
Explanation:Ratio of their initial investments = (1/2 : 1/3 : 1/4) = 6 : 4 : 3.
Let their initial investments be 6x, 2x and 3x respectively.
A:B:C = (6x*2 + 3x*10):(4x*12):(3x*12)
= 42:48:36 = 7:8:6
So B's share = Rs.(378*8/21) = Rs.144

15. Fathers age is 5 times his son's age. 4 years back the father was 9 times older than son.Find the fathers' present age.
Answer: 40
Explanation:Lets assume son's age = x years.
so father's age = 5x years
4 years back:
son age = (x-4) years.
father's age = (5x-4) years
as per Condition given
(5x-4) = 9*(x-4)
=> 5x - 4 = 9x - 36
=> (9x-5x) = 36 - 4
=> 4x = 32 => x = 8
So father's present age = 5 * 8 = 40 years.

17. 2 oranges, 3 bananas and 4 apples cost Rs.15. 3 oranges 2 bananas 1 apple costs Rs.10. what is the cost of 3 oranges, 3 bananas and 3 apples?
Answer: 15
Explanation:Lets assume orange, banana and apple cost is x, y and z respectively.
So, 2 orange + 3 banana + 4 apple =(2x+ 3y + 4z) = 15 -------- (1)
and 3 orange + 2 banana + 1 apple) = (3x+2y+z) = 10 ---------(2)
so from eq. (1) and (2)
5 (orange + banana + apple ) = 25
=> (orange + banana + apple ) = 5
so 3 orange + 3 banana + 3 apple = 3 * 5 = Rs. 15

18. A train started from station 'A' and proceeded towards station 'B' at a speed of 48 Km/hr. Forty-five minutes later another train started from station 'B' and proceeded towards station 'A' at 50 Km/hr. If the distance between the two stations is 232 Km, at what distance from station 'A' will the trains meet?
Answer: 132KM
Explanation:Given, Distance between A and B = 232 KM
Speed of A = 48 km/hr. and Speed of B = 50 Km/hr.
Distance covered by A and B = (48*x)+(50*(x-(45/60)))=232
Therefore, x=11/4
So,distance covered by A = 48*x=48*(11/4)=132 Km

19. Find the time between 5 and 6 o'clock when the two hands of clock are 6 minutes spaces apart.
Answer: 20 8/11 minutes past 5 o'clock
Explanation:In this type of problems the formula is
(5*x+ or - t)*12/11 -----------(Important Point)
Here x is the first interval of given time, and t is spaces apart.
(5 * 5 +6) * 12/11 = 31 *12/11 = 372/11
and
(5 * 5 - 6) * 12/11 = 19 * 12/11 = 228/11 = 20 8/11
