21. R is coded as 2, I as 3, V as 4, E as 7, T as 6 & S as 9. So, RIVETS is coded as 234769.
22. Here M is coded as 6 , A is coded as 2 , L is coded as 1 , E is coded as 7 , therefore male is coded as
6217
23. In the code the letters at odd places are one place ahead & those at even places are one place before
the corresponding letter in the word. So in 35791, 3is written as 4, 5 as 4,7 as 8, 9 as 8 & 1 as 0. The
code becomes 44880.
24. 4 will be written as 5, 5 as 6, 8 as 9, 2 as 1, 3 as 4. So the code is 5914.
25. Code is M as 3, A as 8, D as 9, U as 4, R as, 7 & I as 1. So, MADHRI is coded as 3894781.
