Answer 2

The given question is Puneet was asked to multiply a number by 8 but by mistake, he divided the number by 8. If the correct answer was greater than Puneet's answer by 378,

we have to find what was the number.

let

$\frac{x}{8} = y - - - (1)$

It is given that the real value

which was

$x \times 8$

is 378 more than the punnet's answer y

The correct expression to the given question is

$8x = y + 378 - - - (2)$

From the equations (1) and (2), we get the value as

$x = 8y$

The above term is obtained from equation (1).

substitute x=8y in the equation (2), we get

$8(8y) = y + 378 \\ 64y = y + 378 \\ 64y - y = 378 \\63y = 378 \\ y = \frac{378}{63} = 6$

The value of y is 6.

substitute the value of y in the expression x =8y.

Then the value of x will be

$x = 8(6) \\ x = 48$

Therefore, the final answer to the given question is 48.
