if that odd no is 3 then?
Waisa answer was not in the options! Though question should read '' divisor CAN be'' :)

Consider a triangle. Its longest side has length 12 and another of its sides has length 9. Its area is 54. What is the exact length of its third side?1.15 2.16 3.18 4.20
Longest side is 12 cm and options for the third side are all above 12. Huh ? :roll::splat:

@Ani1308 said:
the the answer would be 108 or 154..but thats bot in the options ..so 204

That is what i am saying Q is ambiguous.

Longest 12..to options me sab >12 kyu?
We have to ask the QP setter.. scrap it. lemme give next

If a carton containing a dozen crockery plates is dropped, then which of the following cannot be the ratio of broken and unbroken plates?
1. 2 : 1 2. 3 : 1 3. 4 : 1 4. 5 : 1

Ratio = m : n.

Check for divisibility of 12 by every (m + n).
So, 3, 4, 5 and 6.
5 cannot divide 12. Hence, 4 : 1 [Option 3]

If there are 10 elements in a set A, how many elements are there in its power set, not including the null set?
1. 729 2. 81 3. 399 4. 1023

12 plates
a, 12-a

R = 12-a/a = 12/a - 1
4:1 cannot be te ratio

2^10 -1 = 1023

10C1 + 10C2 + ... + 10C10 = 2^10 - 1 = 1023.

On reversing a three-digit number, we get a larger number. After adding them together, the result obtained is not a palindrome. The process is repeated with the new number obtained. We get a three-digit number, which is not a palindrome at the end of the 1st or 2nd repetition. At the end of the 3rd repetition, we get a four-digit palindrome. What is the difference between the initial three-digit number and its reverse?

1. 99 2. 100 3. 165 4. 101

power set kya hota hai? koi batao set ka kuch yaad nahi hai ab.

1023 if we exclude null

A set containing any number of elements from the given set A in no particular order!
