Question

A number had to be multiplied by 6 and divided by 5. But by mistake 5 divided by 6 divided by 50; So what should be the true answer?​

Answer 1

Answer:et the original number be x

Thus, the true result is(5×x=5x)

While, according to question the number is divided by 5, which gives us

x/5 as a wrong result

Thus the difference between the actual result and the wrong result is(5x-x/5=24x/5)

Therefore the change in percentage between the actual result and the wrong result is

(Change in result)/(actual result)×100

={(24/x)/5x }× 100

=96%

Let's check this answer,

Suppose the original number is 10,

Therefore, the actual result =(10×5=50)

The wrong result =(10/5=2)

change in result=50–2=48

Change in percent=(48/50)×100

=96%

Thus we can conclude that the above solution

is correct.
