a)1600 b)1792 c)1800 d)1568​

Answer 1

The required "option is d) 1568".

Step-by-step explanation:

Let 2x and 4x be the two parts.

To find, the product of the numbers = ?

According to question,

2x + 4x = 84

⇒ 6x = 84

⇒ x = $\dfrac{84}{6}$

⇒ x = 14

∴ First part = 2 × 14 = 28 and

Second part = 4 × 14 = 56

∴ The product of two numbers

= 28 × 56 = 1568

Thus, the required "option is d) 1568".

Answer 2

Answer:

1568

Step-by-step explanation:

let the two parts be 2x and 4x

2x+4x=84

6x=84

x=84/6

x=14

1st part is 2x=2(14)=28

2nd part is 4x= 4(14)=56

product= 28 x 56= 1568
