Explanation
1 to 2:
Let the number of pieces sold be n and the price
of each piece be p. Then total sales value, v, is
given by pn,
∴
1148 = pn. From the choices given in this
question, rule out 56. Because 56 when reversed
gives 65, which cannot be a factor of 1148. Try
dividing 1148 by the first option, i.e. 82. The
quotient is 14. Check that both, 82 and 14, when
reversed give 28 and 41, whose product is 1148.
Now we have identified the four numbers.
We can now make use of the data that the
inventory reduced by 54. Inventory is the quantify
available in store. i.e. the remainder after having
sold a certain number of pieces. If the inventory
reduces by 54, it means that if actually x pieces
are sold, then ON RECORD, (x + 54) pieces are
sold. Observe that 82 and 28 differ by 54., So, if
28 is the actual number of pieces sold, then 82 is
the value entered. It follows that if 51 was the
actual price per piece, then it was entered as 14.

As X started chasing the thief after 15 minutes,
the thief had gained (15/60)60 = 15 km over X.
the relative speed between the thief and X is 65 
60 = 5 kmph. So, the time taken by X to catch the
thief
is 15/5 = 3 hours. As X had started the
chase at 12.15 p.m. he caught the thief at 3.15
p.m.
4. (2)
The relative speed between the second policeman
and X is 65  60 = 5 kmph. After 3 hours, the
relative distance between
them would be 15 km.

Let the original cost of the diamond be Rs. X, and
let the weight of the diamond be (1 + 2 + 3 + 4) =
10 units. So its original cost varies as 10², i.e. cost
= 100x, say. After the diamond has broken, its
cost becomes (1² + 2² + 3² + 4²)x, i.e. 30x. Thus
the loss in cost is 70x. If 70x corresponds to Rs.
70,000, then the original cost 100x is Rs.1,00,000.
6. (2)
The smaller cubes have a side 1/4
th
the length of
the original side. Thus there are 64 small cubes,
with 4 cubes along one side of the original cube.
The cubes which do not have even a single side
painted are the ones not exposed to the exterior at
all. There are 8 such cubes in the centre.
