Solve the crossword using Roman numerals and the clues are given. Across a ) 31 b ) 16 c ) 19 d ) 29 Down a ) 15 b ) 11 c ) 30 e ) 9 f ) 20

It is given to fill the cross word by converting the given options to Roman numerals. By standard notation of Roman numeral we know that, I → 1 V → 5 X → 10 If the number is repeated then the number is added by itself. If smaller number is written to left of bigger number then we must subtract the smaller number from bigger number. If smaller number is written to right of bigger number then we must add the smaller number to bigger number. Hence, Let us convert Hindu-Arabic to Roman numerals by using standard notation. Thus, Across : 31 → 10 + 10 + 10 + 1 = XXXI 16 → 1 = 10 + 5 + 1 = XVI 19 → 10 + ( 10 - 1 ) = XIX 29 → 10 + 10 + ( 10 - 1 ) = XXIX Down : 15 → 10 + 5 = XV 11 → 10 + 1 = XI 30 → 10 + 10 + 10 = XXX 9 → 10 - 1 = IX 20 → 10 + 10 = XX Therefore, the required answer is obtained.
