3 different numbers A, B, C has 2, 3, 4 factors respectively. when A , B and C are multiplied a new number D is produced that has n number of factors. How many different values of n are possible ?
7 hai kya??
A=2 = a B=3=b^2 C=4 = cd,e^3
now make pairs of A*B*C considering C=cd
possibilities : 1) (a)*(b^2)*(cd) =2*3*2*2=24(wen all different) 2)(a)*(b^2)*(ad) = a*2*b^2*d=18(wen C has 1 digit same as A) 3)(a)*(b^2)*(bd)= a*b^3*d=16(wen C has 1 digit same as B) 4)(a)*(a^2)*(cd)=a^3*c*d=16 (wen digit B is same as A) 5)(a)*(a^2)*(ad)=10
Consider C=e^3 possible pairs 6)a*b^2*e^3=24 7)a*b^2*a^3=15 8)a*b^2*b^3=12 9)a*a^2*a^3=7

To reach next floor of a building using an escalator moving upwards,a person takes 56 seconds and climbs 42 steps of an escalator.When the same person increases his speed,he can climb 94 steps in 30 seconds to reach the next floor.how many steps does the escalator have between the two floors? a)112 b)124 c)144 d)154 Please provide the approach along with solutions.

@saurabhlumarrai no. of steps is identical in both cases...the difference in the no. of steps he climbs (=52) is the equal to neg. diff in the no. of steps the elevator moves...ratio of distances moved by elevator in the two cases is 56:30...we get the actual values to be 112:60...so our answer is (112+42)=(94+60)=154

You can solve this question by assuming values....
m=1
n=2
add 2 to both
m+2/n+2 = 3/4
so x=3
and y=4
check the option that gives you value 2...
P.S. : Method will fail if more than one option gives you the same value...
