How many three digit numbers with distinct digits can be formed such that product of the digits is the cube of a positive integer?a)21 b)24 c)36 d)30 We are required to form different words with the help of the word INTEGER.Let x be the number of words in which I and N are never together and y be the number of words which begin with I and end with R,then x/y is--a)42 b)30 c)6 d)50

@sonamaries7 tried with a series . common diff.=1 (say) a : 5,6,7,8,... am/bm = 6/5 --> m=2 here --> b : 4,5,6,7,... similarly n=4 here and c4=4 --> c1=1
A Gardner planted 729 saplings in such a way that every row had as many saplings as every column.He then decides to plant one new sapling between every two saplings .How many new saplings would he have to plant?1)2180 2)2080 3)1980 4)1880
9 toh ho gye 1to 9 //baaki3,9,8 - 69,6,48,1,19,3,18,4,2ke combos.. approach is like..making eqns are solving them..let d be commn diffso,b1+(m-1)d = a1a1+(m-1)d * 5 = 6* b1+m-1 dc1 + n-1d=b17*a1+ n-1 d = 8 . b1+ n-1 dsolveing these we will get the ration
digit distinct he 1 ques me so hw can u take 811 and 1 to 9...check my sol em getting 30
