ANSWERS
1. 3;
Let the distance be D km. Time is T hours. Speed = S km/hr.
Using Statement I:
D = S × T = (S + 10) (T – 1) S = 10T – 10
Using Statement II:
D = S × T = (S – 8) (T + 1) S = 8T + 8
Using Both:
10T – 10 = 8T + 8 T = 9 Hours, S = 80 km/hr
D = 9 × 80 = 720 Km
So the Answer is (3) ie., using both statements together.
2. 1
√((x - t)/ x) = √(1 – (y/x))
3. 4;
From statement I alone we can find a unique solution as it is given that three integers are consecutive and positive with product 120. So the unique integers will be 4, 5, 6.
From statement II alone we can find a unique solution.
Let the positive integers be a, a + 1, a + 2.
So, a + a + 1 + a + 2 = 15
a = 4 and the integers are 4, 5, and 6.
4. 4; Using Statement I:
We know height of equilateral triangle is
Here height is given so we can find the side and hence the area of triangle.
Using Statement II:
As the co-ordinates of two vertices are given we can find the length of the side of the triangle and hence the area of the equilalteral triangle.
5. 3; Let the length of trains be L1 and L2.
Using Statement I:
We can only find their speeds as 3x and 4x.
Using Statement II:
We can find L1 = 5 × Speed of Trains,
L2 = 6 × Speed of second Trains
Using Both:
L1 = 5 × 3x
L2 = 6 × 4x
Required time to cross each other completely is
(L1 + L2)/ (3x + 4x) = (15x + 24x)/ 7x = 39/7
Hence, the answer is (3).
6. 3; Profit =
7. 4; Data is not sufficient.
8. 4; Data inadequate.
9. 5; (Income - Expenditure)/ Exp*100= P%
Expenditure is 100% in each year and Income% = Exp% + Profit%
Expenditure is 100% in each year and Income% = Exp% + Profit%
10. 1; Profit of A in 2000 = (42*50)/150 = 14 lakhs
Profit of B in 2004 =
