Question 11 of 20
11. Question
A box contains 7 red balls, 5 black balls, 4 orange balls. If three balls are drawn out random, then the probability of getting a balls of different colours
Correct
Answer c
Total probability n(S) = 16C_{3}
Required probability n(E)= 7C_{1} and 5C_{1} and 4C_{1}
P(E) = n(E)/n(S)
P(E) = (7C_{1} and 5C_{1} and 4C_{1}) / 16C_{3}
P(E) = ¼
Incorrect
Answer c
Total probability n(S) = 16C_{3}
Required probability n(E)= 7C_{1} and 5C_{1} and 4C_{1}
P(E) = n(E)/n(S)

Question 12 of 20
12. Question
P, Q and R started a business by investing Rs. 12000, Rs. 18000 and Rs. 25000 respectively. After one year, P invested the same amount as before and Q withdraws 1/3^{rd} of the amount. Find the share of R, if the total profit at the end of two years is Rs. 87000?
If the numerator of the fraction is increased by 15 % and the denominator is decreased by 16 %, then the resultant fraction is 23/35. Find the original fraction?
Correct
Answer d
Let the original fraction be x/y,
[X*(115/100)]/[y*(84/100)] = 23/35
x/y = (23/35)*(84/115)
x/y = (12/25)
Incorrect
Answer d
Let the original fraction be x/y,
[X*(115/100)]/[y*(84/100)] = 23/35
x/y = (23/35)*(84/115)
x/y = (12/25)
Question 14 of 20
14. Question
In what ratio water be mixed with milk to earn a profit of 30 % by selling the mixture at cost price?
Correct
Answer b
Let the cost price be Rs. 1
Selling price of mixture = Rs. 1
Cost price of mixture = 1*(100/130) = 10/13
= > – (10/13) : – (3/13)
= > 10 : 3
Incorrect
Answer b
Let the cost price be Rs. 1
Selling price of mixture = Rs. 1
Cost price of mixture = 1*(100/130) = 10/13
= > – (10/13) : – (3/13)
= > 10 : 3
Question 15 of 20
15. Question
A boat covers 48 km in 6 hours along the stream and the same distance in 8 hours against the stream. Find the speed of stream and speed of boat in still water?
Correct
Answer c
Speed of downstream = 48/6 = 8 km/hr
Speed of upstream = 48/8 = 6 km/hr
Speed of boat = (1/2) (Speed of downstream + Speed of upstream)
= > (1/2) (8 + 6) = 14/2 = 7 km/hr
Speed of stream = (1/2) (Speed of downstream – Speed of upstream)
= > (1/2) (8 – 6) = 2/2 = 1 km/hr
Incorrect
Answer c
Speed of downstream = 48/6 = 8 km/hr
Speed of upstream = 48/8 = 6 km/hr
Speed of boat = (1/2) (Speed of downstream + Speed of upstream)
= > (1/2) (8 + 6) = 14/2 = 7 km/hr
Speed of stream = (1/2) (Speed of downstream – Speed of upstream)
= > (1/2) (8 – 6) = 2/2 = 1 km/hr

Find the difference between the total revenue of shop D and shop E?
Correct
Answer c
The total revenue of shop D
= > 45*40000 = Rs. 1800000
The total revenue of shop E
= > 65*30000 = Rs. 1950000
Required difference = 1950000 – 1800000 = 150000
Incorrect
Answer c
The total revenue of shop D
