Question

the square of which of the following numbers is the difference between the 49th even Number after 1575 and 70th even Number before 1028

Answer 1

Answer:

28

Step-by-step explanation:

Hi,

Let the number be 'x'

49th even number after 1575 will be same as 49th even number after 1574

= 1574 + 2* 49 = 1574 + 98

= 1672

70 th even number before 1028 will be =

1028 - 70*2

= 1028 - 140

= 888,

Given x² = 1672 - 888

⇒ x² = 784

⇒ x = 28 .

Hope, it helps !
