Correct Answer: 68

Solution : Given:
REDUCE = 56, RECYCLE = 71.

Add the place value of the letters to get the required code –.
Like the place value of the letters REDUCE; R→18; E→5; D→4; U→21; C→3; E→5
REDUCE→18 + 5 + 4 + 21 + 3 + 5 = 56
Thus, REDUCE is coded as 56
And, the place value of RECYCLE; R→18; E→5; C→3; Y→25; C→3; L→12; E→5
RECYCLE→18 + 5 + 3 + 25 + 3 + 12 + 5 = 71
Thus, RECYCLE is coded as 71.
Similarly, follow the same pattern for REUSE; R→18; E→5; U→21; S→19; E→5
REUSE→18 + 5 + 21 + 19 + 5 = 68

Thus, the code for REUSE is 68. Hence, the second option is the correct answer.
