Question is based on code language. Find the correct answer from the four alternatives given.

lf the word ’P H O N E’ is coded as ’S K R Q H’, how will ‘R A D I O’ be coded?

विकल्प

  • S C G N H

  • V R G N G

  • U D G L R

  • S D H K Q

MCQ

उत्तर

U D G L R

Explanation;

Hint:

If PHONE is coded as S K R Q H

Find that code for R A D I O

We find that we get the code, by 3 letter alphabetically so. from P. skipping Q and R. we get S

Similarly, from H, skipping I and J, we get K

Like wise for R A D I O. skipping the 2 alphabets,

From R skip S and T → U

From A skip B and C → D

From D skip E and F → G

From l skip J and K → L

From O skip P and Q → R

∴ So, we get UDGLR
