abhishek maini  (10 years ago)

we have to find all the 3 number combinations such tht they form 36.so we cn do it like:
1*4*9=36 number of ways it cn be done is 6.
1*6*6=36 number of ways it cn be done is 3.(166,616,661)
2*3*6=36 number of ways or arrangement of 2,3,6 yields 6 ways.
2*9*2=36 number of ways it cn be done is 3.
3*4*3=36 number of ways it cn be done is 3.
so adding all of the above we have 6+3+6+3+3=21 ways

1)series is 1,9,81,729

2)let n =2, so ( 1(9^2-1)/9-1 )/6 = 80/(8*6) = 80 / 48 .
so divisible by 2 is not an answer.

3)let n=3, so ( 1(9^3-1)/9-1 )/6 = 729-1/(8*6) = 728/48 =2*2*2*7*13/2*2*2*2*3
so divisible by 3 is not an answer ,
somebody try remaining 2 options .

ans-1
because it follows the pattern as 1st-no*2nd-no=3rd no
and rhs part will be equal to the 2nd-no 3rdno,i.e it will be in the
form a*b*c=bc
so only 2*4*8=48
