Explain dude?

is it 74?????.......vats the answer??????

the answer is not given....

360= 2^3 x 3^2 x 5^1

now look for highest power of 5,because the no of 2s and 3's will be less than 5

520/5=104/5=20/5=4/5

=104+20+4=128

generally you will get answer like this...but you must also check for 2's and 3's...in this question 2's should be more than 384 and 3's should be more than 256..which they are hence 128 is the answer

i think it shud be 74.....may b im nt correct.....but 360=5x3^2x2^3 so we will check for 5,9 n 8.....n the min will be for 8....i.e 74.....

remember 2 is coming thrice and 3 twice....i mean divide the power of 2 by 3 n 3 by 2.........

Count the number of 3's,2's and 5's...2 and 3 comes 128 and 2 comes out as more than 128..We need the combination of them...So its total of 128 only..
360=10*36==>5*2*9*4==>5*2^3*3^2...i hope this is clear..

hi how to do this ques
two friends were discussing their marks in an exam while doing so they found that they got the same prime factors although raveesh got a score which had two more factors than harish. if their marks are represented by one of the options what are they

c.40,80
d. 20,60


ans. c

go through options as mentioned in prob itself
a)2x3x5, 2^2x3x5
=>2x2x2=>8
=>3x2x2=>12
b)2^2x5, 2^4x5
=>3x2=6
=>5x2=10
c)2^3x5, 2^4x5
=>4x2=8
=>5x2=>10
so c is the answer

i don't understand >2x2x2=>8
=>3x2x2=>12 thing.
plz explain .

its just the formula to find the no of divisors..
if N=(x^a)(y^b) where x and y are prime facors then no of divisors is (a+1)(b+1)

5000* 2 * pi * r = 11000

r = 7/20 = 0.35 m = 35cm
