Answer : Any two statements together.
Explanation : Explanations : Let speed of boat in sill water be x kmph and velocity of stream be y kmph respectively.
Explanation : Explanations : Let speed of boat in sill water be x kmph and velocity of stream be y kmph respectively.
So, from I , we get x+y = 5kmph
From II, it given y = 2x/3 , we get x = 3kmph and y = 2kmph
From III, w get, x - y = 2.5 kmph
Therefore, to find out the speed of the boat any two statements together is sufficient.

1) | I only | 2) | I and II only |
3) | II and III only | 4) | I and III only |
5) | None of these |
Answer : I only
Explanation :
Explanation :
Explanation:
P = Rs. 5000 & T = 2 years.
I. S.I. on Rs. 5000 in 5 years is Rs. 2000.
(5000 x R x 5)/100 = 2000 or R = 8.
Thus I only gives the answer.
Correct answer is (1).

1) | I and II only | 2) | II and III only |
3) | All I, II and III | 4) | Any two of the three |
5) | None of these |
Answer : All I, II and III
Explanation :
Explanation :
Explanation:
I. Material cost = Rs. 2.50 per m2
II. Labour cost = Rs. 3500.
III. Total cost = Rs. 14,500.
Let the area be A sq. metres.
Material cost = Rs. (14500 - 3500) = Rs. 11,000.
5A/2 = 11000 or A = (11000 x 2 )/5 = 4400 m2.
Thus, all I, II and III are needed to get the answer.
Correct answer is (3).
