Question

$\text{Solve the following riddle by finding the sum of}\text{A + B from the following expression:}$

• A. A + B = 11
• B. A + B = 6
• C. A + B = 9
• D. A + B = 14

Answer 1

The correct option is A A + B = 11

$\text{To solve the riddle,}\text{we have to find the difference of}\frac{7}{10}-\frac{3}{5}$

Now to find the difference, we have to convert the fractions to like fractions first.

$\text{The fraction}\frac{7}{10}\text{can be represented as:}$


$\text{Similarly,}\text{the fraction}\frac{3}{5}\text{can be represented as:}$


$\text{So, we can write:}\frac{7}{10}-\frac{3}{5}=\frac{7}{10}-\frac{6}{10}$

$\text{Calculating}\frac{7}{10}-\frac{6}{10}\text{, we get:}$


$\text{Comparing the fraction}\frac{1}{10}\text{with the}\text{riddle given, we find:}$



$\text{Hence, A = 1 and B = 10}$

$\therefore A+B=1+10=11$
