A number, K, is a positive integer with the special property that 3 times its unit is equal to 2 times
its 10 digit. How many such numbers exist between 10 & 99?
(A) 2
(B) 3
(C) 4
(D) 5

• b.3 nos are 32,64,96

• let the number be 10x+y=k
  by the question 2x=3y
  so,k=16y=a number divisible by 16 between 10 & 99 and 2/3 of y must be an integer since x is an integer...so, k=32,64,96
  number of such no.s is 3
  thank you..
  thank

• 32, 64, 96 are the numbers. The answer is 3

• let 'k' be a no. = 10x+y...
  so, 3y=2x
  so, no, =10x+y=15y+y=16y..now y has to be even such that x is an integer
  so y can attain 3 values=2,4,6
  so the nos. are 32,64,96...ans is (B)3
