Question

a boy was asked to multiply a number by 5 upon 11 instead he divided by 5 upon 11 and thereby his answer exceeded the correct answer by 192 what is the correct answer give meaningful answer​

Answer 1

Answer:

sry mate the question not clear

Answer 2

The correct answer is 50.

Given:

A boy was asked to multiply a number by 5/11.

Instead, he divides it by 5/11 and so his answer exceeded the correct answer by 192.

To Find:

The correct answer.

Solution:

Let us assume that the original number is 'x'.

Let us assume that the original answer obtained on correctly following the instructions is A$_{1}$.

We are given that a boy was asked to multiply a number by 5/11.

Hence, the answer obtained on correctly following these instructions is,

A$_{1}$ = 5/11 × x

⇒A$_{1}$ = 5x/11         ...............................(I)          

But instead, the boy divides the number by 5/11. Hence the original answer exceeds 192. Writing this in terms of an equation, we have:

A$_{1}$ + 192 = x / (5/11)

⇒ A$_{1}$ + 192 = 11x/5

Substituting the value of A$_{1}$ from equation (I) into the above equation, we have:

5x/11 + 192 = 11x/5

⇒ 192 = 11x/5 - 5x/11

⇒ 192 = (121x-25x)/55 = 96x/55

⇒ 192 × 55/96 = x

⇒ x = 110.

Hence, the original number is 110.

To find the correct answer A$_{1}$, we need to multiply 110 by 5/11.

⇒A$_{1}$ = 110 × 5/11 = 50.

Hence, the correct answer is 50.
