2). If X^Y denotes X raised to the power of Y, find out last two

digits of (2957^3661)+(3081^3643)

Ans; 98 is the ans
7^1 is 7
and
5*1=5
so last to digit of (2957^3661) is 57

same for
1^3 is 1
8*3=24 unit digit of 24 is 4
last 2 digit of(3081^3643) is 41
41+57=98....

3). if f(x) is a function for all real numbers x holds good for maximum of 2x+4 and 12+3x..then wat is the value of x so that f(x) is equal to 2x+4..Ans is -9

Ans: ans is -9

maximum (2x+4 ,12+3x)
and ques says maximum is 2x+4
if x= -9 2x+4 = -14 and 12+3x= -15 maximum is -14

so ans is -9

4). 15 women or 10 men complete in 55 days..how many days 4 women and 5 men vil take

1 Women= 10/15 Men
4 women= 4*10/158=8/3
total= 5+8/3 men= 23/3
chain rule
55*10 = (23/3)*D
D= 550*3/23 =71.73 days

5). My flight takes off at 2am from a place at 18N 10E and landed 10 Hrs later at a place with
coordinates 36N70W.What is the local time when my plane landed? a) 6:00 am b) 6:40 am c) 7:40 am d)
7:00 am e) 8:00 am
