Answer:

Question :-

➳ Units digit of a 2-digit number is 3 times its tens digit. If the units digit is 6, find the number.

Given :-

➳ Units digit of a 2-digit number is 3 times its tens digit. The units digit is 6.

To Find :-

➳ What is the number.

Solution :-

Let,

$\mapsto \bf Ten\: Digit =\: a$

Now, it is given that :

$\bigstar$ Units digit of a 2-digit number is 3 times its tens digit. So,

$\mapsto \bf Unit\: Digit =\: 3a$

According to the question :

$\bigstar$ The unit digit is 6.

So,

$\implies \bf 3a =\: 6$

$\implies \sf 3a =\: 6$

$\implies \sf a =\: \dfrac{\cancel{6}}{\cancel{3}}$

$\implies \sf a =\: \dfrac{2}{1}$

$\implies \sf\bold{\purple{a =\: 2}}$

Hence, the required number is :

✫ Ten Digit :

$\mapsto \sf Ten\: Digit =\: a$

$\mapsto \sf\bold{\red{Ten\: Digit =\: 2}}$

✫ Unit Digit :

$\mapsto \sf Unit\: Digit =\: 3a$

$\mapsto \sf Unit\: Digit =\: 3 \times 2$

$\mapsto \sf\bold{\red{Unit\: Digit =\: 6}}$

$\therefore$ The number is 26 .
