Complete the table. 21 XXI 10 + 10 + 1 22 23 24 25 26 XXVI 10 + 10 + 5 + 1 27 28 29 30 XXX

We need to fill the blanks in the table. By observing the given table we know that, I represents 1 . V represents 5 . X represents 10 . Thus, 22 → 10 + 10 + 1 + 1 = XXII 23 → 10 + 10 + 1 + 1 + 1 = XXIII 24 → 10 + 10 + ( 5 - 1 ) = XXIV 25 → 10 + 5 = XV 27 → 10 + 10 + 5 + 1 + 1 = XXVII 28 → 10 + 10 + 5 + 1 + 1 + 1 = X XVIII 29 → 10 + 10 + 10 - 1 = XXIX 30 → 10 + 10 + 10 = XXX Therefore, 21 XXI 10 + 10 + 1 22 XXII 10 + 10 + 1 + 1 23 XXIII 10 + 10 + 1 + 1 + 1 24 XXIV 10 + 10 + ( 5 - 1 ) 25 XXV 10 + 10 + 5 26 XXVI 10 + 10 + 5 + 1 27 XXVII 10 + 10 + 5 + 1 + 1 28 XXVIII 10 + 10 + 5 + 1 + 1 + 1 29 XXIX 10 + 10 + ( 10 - 1 ) 30 XXX 10 + 10 + 10 Hence, the required answer is obtained.

Let us fill the given table. We know that, I represents 1 . V represents 5 . X represents 10 . L represents 50 . Writing the Roman numerals we get, 30 → 10 + 10 + 10 = XXX 31 → 10 + 10 + 10 + 1 = XXXI 32 → 10 + 10 + 10 + 1 + 1 = XXXII 33 → 10 + 10 + 10 + 1 + 1 + 1 = XXXIII 34 → 10 + 10 + 10 + ( 5 - 1 ) = XXXIV 35 → 10 + 10 + 10 + 5 = XXXV 36 → 10 + 10 + 10 + 5 + 1 = XXXVI 38 → 10 + 10 + 10 + 5 + 1 + 1 + 1 = XXXVIII 39 → 10 + 10 + 10 + ( 10 - 1 ) = XXXIX 40 → 50 - 10 = XL Writing the missing values in the table we get, 31 XXXI 10 + 10 + 10 + 1 32 XXXII 10 + 10 + 10 + 1 + 1 33 XXXIII 10 + 10 + 10 + 1 + 1 + 1 34 XXXIV 10 + 10 + 10 + ( 5 - 1 ) 35 XXXV 10 + 10 + 10 + 5 36 XXXVI 10 + 10 + 10 + 5 + 1 37 XXXVII 10 + 10 + 10 + 7 38 XXXVIII 10 + 10 + 10 + 5 + 1 + 1 + 1 39 XXXIX 10 + 10 + 10 + ( 10 - 1 ) 40 XL 50 - 10 Hence, the required answer is obtained.

Complete the table. 1 I 1 2 II 1 + 1 3 III 1 + 1 + 1 4 IV 5 - 1 5 V 5 6 VI 5 + 1 7 VII 8 VIII 9 IX 10 - 1 10 X

We need to fill the missing values in the given table. By observing the given table we know that, I represents 1 . V represents 5 . X represents 10 . Thus, VII = 5 + 1 + 1 = 7 VIII = 5 + 1 + 1 + 1 = 8 X = 10 Now, filling the table with the answer we get, 1 I 1 2 II 1 + 1 3 III 1 + 1 + 1 4 IV 5 - 1 5 V 5 6 VI 5 + 1 7 VII 5 + 1 + 1 8 VIII 5 + 1 + 1 + 1 9 IX 10 - 1 10 X 10 Therefore, the required answer is obtained.

Complete the table. 11 XI 10 + 1 12 13 14 XIV 10 + 4 15 16 17 18 19 XIX 10 + 9 20 XX 10 + 10

We need to fill the missing values in the given table. By observing the given table we know that, I represents 1 . V represents 5 . X represents 10 . Thus, 12 → 10 + 1 + 1 = XII 13 → 10 + 1 + 1 + 1 = XIII 15 → 10 + 5 = XV 16 → 10 + 5 + 1 = XVI 17 → 10 + 5 + 1 + 1 = XVII 18 → 10 + 5 + 1 + 1 + 1 = XVIII Writing the answer in the table we get, 11 XI 10 + 1 12 XII 10 + 1 + 1 13 XIII 10 + 1 + 1 + 1 14 XIV 10 + 4 15 XV 10 + 5 16 XVI 10 + 5 + 1 17 XVII 10 + 5 + 1 + 1 18 XVIII 10 + 5 + 1 + 1 + 1 19 XIX 10 + 9 20 XX 10 + 10 Hence, the required answer is obtained.

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.
