1. find last 2 digits of the expression
a) 101 x 102 x 103 x 197 x 198 x 199
b) 65 x 29 x 37 x 73 x 81 x 87
2. If u form a subset if integers chosen from between 1 to 3000 such that no two integers add up to a multiple of nine , what can be
maximum no. of elements in the subset [P40Q65]
a)1668 b) 1332 c) 1333 d)1334
DOUBT.....I'm getting different answere
3. the series of numbers(1, 1/2, 1/3 , ...1/1972) is taken .
now two numbers are taken from this series ( the first two) say x,y.
Then the operation x+y+x.y is performed to get a consolidated number.
The process is repeated. What will be the value of the set after all
the numbers are consolidated into one number. [P40Q66]
a) 1970 b) 1971 c ) 1972 d)none
DOUBT....couldn't understand the question
a) 101 x 102 x 103 x 197 x 198 x 199
b) 65 x 29 x 37 x 73 x 81 x 87

( it took me about 1 min also) so i think it is not very time consuming if you don't know the shortcut.
