Question

if 15+10 = VIII; 8+6= X; 19+12= X, then what is the value of 9+4= ?

Answer 1

Step-by-step explanation:

(15)^2-(10)^2= 125 (1+2+5= VIII)

8^2-6^2= 28( 2+8= X)

Similarly, 9^2-4^2= 65 (6+5= XI)

Hope it helps you

Answer 2

Given :

15 + 10 = VIII; 8 + 6 = X, 19 + 12 = X

To find :

The value of 9 + 4.

Solution:

• The Logic :

15 + 10 = VIII

→ 15²- 10²

→ 225 - 100

→ 125

→ 1 + 2 + 5 = 8

• 8 in roman numeral is VIII

So, 15 + 10 = VIII

Similarly, Let's find out the code for 9 + 4 = ?

→ 9²- 4²

→ 81 - 16

→ 65

→ 6 + 5 = 11

Hence,

• 11 in roman numeral is XI

So, 9 + 4 = XI
