If x = 0.abcd, where a, b, c, and d each represent a nonzero digit of x, what is the value of x ? (1) a/2 = b = 2c = 4d (2) The product of a and d is equal to the product of b and c. Struggling to solve this and get A. Can you please let me know the concept behind this?

If x = 0.abcd, where a, b, c, and d each represent a nonzero digit of x, what is the value of x ?(1) a/2 = b = 2c = 4d > multiply by 2: a=2b=4c=8d > since each represent a nonzero single digit then d can only be 1 (if it's more than 1 a will be more than 10) > a=8, b=4, c=2 and d=1. Sufficient. (2) The product of a and d is equal to the product of b and c > multiple values of x are possible: 0.1111, 2222, 1221, ... Not sufficient. Answer: A. Similar question to practice: ifx0rstuwhererstandueachrepresentanonzero109735.htmlHope it helps.

Great Question Here x=0.abcd To get x we need a,b,c,d Statement 1 a/2=b=2c=4d multiplying by 2 throughout a=2b=4c=8d hence a must be divisible by 8 hence the only possible value of x is 0.8421 hence sufficient Statement 2 using test cases x=0.1111 x=0.2424 hence not sufficient Hence A
