If ‘DELHI’ is coded as ‘15’, ‘RAJASTHAN’ is coded as ’45’, then ‘MUMBAI’ is coded as 1) 24 2) 21 3) 18 4) None

• Answer=21...This is because we get the value as sum of the total no of characters used.....In 'DELHI' there are 5 characters so value=1+2+3+4+5=15 also in 'RAJASTHAN' there are 9 characters so value=1+2+3+4+5+6+7+8+9=45.So 'MUMBAI' there are 6 characters so value=1+2+3+4+5+6=21...So option will be 2)21....

• DELHI- 4 5 12 8 9=sum of last digit=28,28-no of letter=28-5=23->2+3=5.
  So last digit should be 5
  RAJASTHAN -18 1 10 1 14 15 8 1 14=32-9=23->2+3=5
  MUMBAI- 13 16 13 2 1 9->24-6=18->8+1=9
  sO LAST DIGIT SHOULD BE 9. so answer is none

  so mumbai 6 letters therefore ans is 1+2+3+4+5+6=21
  ans is 21
