Question

2 continue odd number sum is 40 .now wath the digit

Answer 1

Answer:

Required odd numbers are 19 and 21.

Step-by-step explanation:

Let the given consecutive add numbers are 2a - 1 & 2a + 1. { 2a ± 1 }

Here,

Sum of both the numbers is 40.

= > ( 2a - 1 ) + ( 2a + 1 ) = 40

= > 2a - 1 + 2a + 1 = 40

= > 4a = 40

= > a = 40 / 4

Therefore : Numbers are -

• 2a - 1 = 2( 10 ) - 1 = 20 - 1 = 19
• 2a + 1 = 2( 10 ) + 1 = 20 + 1 = 21

Hence, required odd numbers are 19 and 21.
