Answer 2

Answer:

219/3 = 73

438/6 = 73

657/9 = 73

Method:

If any number LQ is multiplied by 9, right most digit of the product will be (10 - Q).

So, from JKL/9 = LQ,

we get, L = 10 - Q

LQ can be mathematically represented as

10L + Q = 10(10 - Q) + Q = 100 - 9Q

Since PQR/6 = LQ,

PQR = 6LQ = 6(100 - 9Q) = 600 - 54Q

We now try various values for Q such as 1, 2, 3, .... , etc, till the middle digit of the product turns out to be the same as the value of Q used. We get the correct answer for Q at the very third attempt, namely 3. Hence,

L= 10 - 3 = 7.

That is it.
