In climbing a round pole of 80 meters height, a monkey climbs 5 meters in a minute and slips 2
meters in the alternate minute. To get to the top of the pole, the monkey would take : | [
"58 minutes",
"51 minutes",
"63 minutes",
"54 minutes"
] | B | a monkey climbs 5 meters in one min & slips 2m in other min.
therefore the monkey reach 3meters in 2min
3m=2min
25*3m=25*2min - >75m=50min
hence the remaining 5m jumps the monkey in 1min to reach original height
so 51 min

Rose is two years older than Bruce who is twice as old as Chris. If the total of the age of Rose, B and Chris be 27 years, then how old is Bruce ? | [
"8 years",
"16 years",
"10 years",
"12 years"
] | C | Let Chris's age be x years. Then, Bruce's age = 2x years.Rose's age = (2x + 2) years.
(2x + 2) + 2x + x = 27
5x = 25
x = 5.
Hence, Bruce's age = 2x = 10 years.

What is the greatest prime factor of 4^15 - 2^28? | [
"11",
"5",
"2",
"3"
] | D | I'm happy to help with this.
We know 4 = 2^2, so 4^15 = (2^2)^15 = 2^(2*15) = 2^30
That takes advantage of a law of exponents that says (a^n)^m = a^(n*m)
So, 4^15 - 2^28 = 2^30 - 2^28 = 2^(28 + 2) - 2^28 = (2^28)*(2*2) - 2^28 = (2^2 - 1) *(2^28)
