# If 0, 1, 2, 3, ….., 9 is written as a, b, c, d, ….. j, then find dc x f – (bf-d)xd :

- abc
- abb
- bce
- bcf

**Answer: (3) bce**

**Explanation:-**

0 1 2 3 4 5 6 7 8 9

a b c d e f g h i j

dc x f – (bf – d) x d

Put the value of b = 1, c = 2, d = 3 & f = 5.

Then, the value of dc x f – (bf – d) x d = 32 x 5 – (15 – 3) x 3

= 160 – (12) x 3

= 160 – 36

= 124

Then, 124 is coded as** bce. **

Hence, the correct answer is option (3) bce.
