Question

a,b,c,d and e are 5 consecutive even numbers. if the sum of a and d is 198. what is the sum of all numbers ?​

Answer 1

Answer :

The sum of all numbers = 500

According to the question :

Let the number be ' x '

⋆ 5 consecutive even numbers = x, ( x + 2 ), ( x + 4 ), ( x + 6 ), ( x + 8 )

⋆ A = (x) , B = (x + 2) , C = (x + 4) , D = (x + 6) , E = (x + 8)

⋆ Sum = Addition

According to the condition :

• A + D = 198
• A = ( x ) , D = ( x + 6 )

Equation :

→ x + ( x + 6 ) = 198

→ 2x + 6 = 198

→ x = 198 - 6 / 2

→ x = 192 / 2

→ x = 96

☞ A = x = 96

☞ B = x + 2 = 96 + 2 = 98

☞ C = x + 4 = 96 + 4 = 100

☞ D = x + 6 = 96 + 6 = 102

☞ E = x + 8 = 96 + 8 = 104

To find :

Sum of all ,

=> 96 + 98 + 100 + 102 + 104

=> 500
