I had some sweets (less than 80) with me. I distributed them among Sachin and Saurav. After distributing the sweets, it was found that both of them had got a different number of sweets, but both the numbers had the same unique properties. Both the numbers could be expressed as the sum of the squares of two different numbers and also as the difference of the cubes of two different numbers.
26 + 37 = 63. Choice (3)
Directions : These questions are based on the data given below.
Directions : These questions are based on the data given below.
The number of toffees will be {(LCM of 4&5)k-1}i.e, 20k-1 since this is the number between 80 and 100, it can only be for k = 5 or 99 toffees.
If they are divided among 6 people, there will be three left.
Directions : These questions are based on the data given below.
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.
