Question

The product of two numbers is 2979.If one of the numbers is
9, the difference between the two number is-
A)322 B)340 C)349 D)331

Answer 1

Answer :-

• The difference between the two numbers is 322 ( Option - A ).

Given :-

• Product of two numbers = 2979.
• One of the number = 9

To find :-

• Difference between two numbers?

Solution :-

Let the number be x

So, The equation will be :-

➜ x × 9 = 2979

➜ $\bf \dfrac{2979}{9}$

➜ x = 331

So, The 2nd number is 331.

Difference between the two numbers :-

➜ 331 - 9 = 322.

Hence, The difference between the two numbers is 322.

Verification :-

➜ x × 9 = 2979

By replacing, 331 in place of x, We get :-

➜ 331 × 9 = 2979

➜ 2979 = 2979

LHS = RHS

Hence, Verified.

Answer 2

Given:-

• Product of two numbers is 2979.
• One of the number is 9.

To Find:-

• Difference between two numbers is =?

Solution:-

Let the number be x.

According to the question,

$\sf \implies x \times 9 = 2979$

$\sf \implies x = \frac{2979}{9} \\ \\ \sf \implies x = 331$

So,the second number is 331.

Difference = 331 - 9 = 322.

Hence，322 is the difference number.
