Question

5. Jitu is asked to divide a number by 10. Instead of dividing by 10, he multiplies the number by 10 and gets 300 as the answer. By what number should Jitu now divide 300, to get the CORRECT answer?
A. 10 B. 20 C. 30 D. 100

Answer 1

Jitu must divide 300 by 10 , to get the CORRECT answer

Given :

• Jitu is asked to divide a number by 10.

• Instead of dividing by 10, he multiplies the number by 10 and gets 300 as the answer

To find :

The number should Jitu now divide 300, to get the CORRECT answer

A. 10

B. 20

C. 30

D. 100

Solution :

Step 1 of 3 :

Form the equation to find the CORRECT answer

Let the number in CORRECT answer is x

By the given condition

$\displaystyle \sf{ 10x = 300 }$

Step 2 of 3 :

Find the number in CORRECT answer

$\displaystyle \sf{ 10x = 300 }$

$\displaystyle \sf{ \implies x = \frac{300}{10} }$

$\displaystyle \sf{ \implies }x = 30$

So the number in CORRECT answer = 30

Step 3 of 3 :

Find the number should Jitu now divide 300, to get the CORRECT answer

Let Jitu must divide 300 by m , to get the CORRECT answer

The number in CORRECT answer = 30

By the given condition

$\displaystyle \sf{ \frac{300}{m} = 30 }$

$\displaystyle \sf{ \implies }m = \frac{300}{30}$

$\displaystyle \sf{ \implies }m = 10$

So Jitu must divide 300 by 10 , to get the CORRECT answer

Hence the correct option is A. 10

Answer 2

Answer:

Jitu should divide 300 by 100.

Step-by-step explanation:

If we divide by 10, we get the number which is 30.

To get the expected answer, we should divide this also by 10.

Since 10 x 10 = 100, we can divide 300 by 100.
