1.2^2014 - 2^2013
= 2^2013(2^1 - 1)
=2^2013 x 1 = 2^2013
Ans 3
Logic is initial diff 2 3 5 8
Logic is initial diff 2 3 5 8
So 2+3=5
3+5=8
5+8=13
So next 13+21=34
3+5=8
5+8=13
So next 13+21=34
4.
15c2+19c2-11c2 /25c2 =221/300
15c2+19c2-11c2 /25c2 =221/300
here 11c2 comes from
15apples ahai 4 kharab hai
2 apple chose krne hai ache apples me se .. so 11c2
15apples ahai 4 kharab hai
2 apple chose krne hai ache apples me se .. so 11c2
4. Probaility for 2 apples = 15c2/25c2
for gud fruit = 19c2/25c2
for gud apple = 11c2/25c2
prob. for apple or gud fruit = 15c2/25c2 + 19c2/25c2 - 11c2/25c2 = 221/300
5.5c1×14c1/15c2
Q 5
(5C1*10C2)/15C2
=10/21 solve it by urslf
6.A= 20000*24
B= 15000*24
C= 20000*18
C= 20000*18
ratio of A:B:C= 4:3:3
total 10x= 25000
share of B= 25000/10x *3x=7500
share of B= 25000/10x *3x=7500
pehle sab me se 3 zeroes kat do (divide by 1000)
20*24: 15*24: 20*18
ab 6 se divide karo...
20*4 : 15*4 : 20*3
ab 5 se divide karo...
4 * 4 : 3*4 : 4*3
ab 4 se divide karo...
4 : 3 : 3
Ans 8: all are cubes except 196
and Q9
3+6+2=11
4+8+2=14
5+5+1=11
2+6+3=11
3+4+4=11
2+8+4=14
now you can see the series 11 14 11 11 11 14
so 263 is odd here ..... there sud be 14 not 11
4+8+2=14
5+5+1=11
2+6+3=11
3+4+4=11
2+8+4=14
now you can see the series 11 14 11 11 11 14
so 263 is odd here ..... there sud be 14 not 11
ans 9 :
multiply 1st n last u will get middle one....
Q9.
middle digit is product of 1st and 3rd digit:
362: 3*2=6; 482:4*2=8 ; 551: 5*1=5 ; 263: 2*3=6; 344:3*4=12(wrong); 284: 2*4=8, therefore 344 is odd one out
10.
Let the speed of the boat in still water = x km/hr
Let the speed of the boat in still water = x km/hr
Speed of the current = 2 km/hr
Then, speed downstream = (x+2) km/hr
speed upstream = (x-2) km/hr
Total time taken to travel 10 km upstream and back = 55
minutes =55/60 hrs = 11/12
=> 10/x-2 + 10/x+2 = 11/12
x=22kmph
=> 10/x-2 + 10/x+2 = 11/12
x=22kmph
