Question

Find the sum of all 3-digit numbers which leave remainder 3 when divided by 13.

Answer 1

$\huge {\red {\ddot {\smile }}} {\huge {\pink {\ddot \smile}}} {\huge {\purple {\ddot {\smile}}}} {\huge {\orange {\ddot {\smile }}}} {\huge {\blue {\ddot {\smile}}}} {\huge {\green {\ddot {\smile}}}}$

$\huge {\red {\mathtt {\overbrace {\pink {\underbrace{Hey\:Mate....!!!}}}}}}$....

$\huge {\red {\ddot {\smile }}} {\huge {\pink {\ddot \smile}}} {\huge {\purple {\ddot {\smile}}}} {\huge {\orange {\ddot {\smile }}}}$

$\huge {\red {\mathtt {\overbrace {\pink {\underbrace{ANSWER}}}}}}$....

↪ Let's try some numbers , such as ,

↪ 2 ÷ 3 leaves the remainder 3 .

↪ 5 ÷ 3 leaves the remainder 3 .

↪ 10 ÷ 3 leaves the remainder 3 .

So , we have got all the three numbers ,

So the sum is , 2 + 5 + 10 = 17

ANSWER = 17
