Answer : C
Explanation
Let the required time be x years. Then, 8000+8000*12/100*x= 9100+9100*10/100*x => 50x =1100 => x= 22 years
Answer : A
Explanation
given exp. = { 1+ 1/ (1+1/(4/3)} /11/7
= { 1+ 1/( 1+3/4)} /11/7
= [ 1+ 1/(7/4)]/11/7
= (1+4/7) /11/7
= 11/7 /11/7
= 1
Answer : A
Explanation
y = 12846 x 593 + 12846 x 407 = 12846 x (593 + 407) = 12846 x 1000 = 12846000

Answer : C
Explanation
100 years contain 5 odd days. ∴ Last day of first century is Friday. 200 years contain (5*2) = 3 odd days. ∴ Last day of second century is Wednesday. 300 year contain (5*3) =15=1 odd day. ∴ Last day of third century is Monday. 400 year contain 0 odd days. ∴ Last day of fourth century is Sunday. The cycle is repeated. ∴ Last day of a century can't be Tuesday or Thursday or Saturday.

Q 8 - At what time between 2 and 3 o' clock will the hands of a clock be together?
Answer : A
Explanation
At 2 o' clock, the hour hand is at 2 and minute hand is at 12 i.e. they are 10 min spaces apart. The minute hand has to gain 10 minute spaces over the hour hand to be together. The minute hand gains 55 mins in 60 mins. ∴ It will gain 10 mins in 60/55 * 10 min = 120/11 minutes. Hence the hands will coincide at 120/11 minutes past 2.
