are? (3 marks)
0 25,30
O 50,55
O 60,65
O 40,45​

Answer 1

Answer:

60 and 65

Step-by-step explanation:

Given sum of two consecutive multiples of 5 = 125

let the numbers be 5n and 5(n+1)

=> 5n + 5(n+1) = 125

=> 5n + 5n + 5 = 125

=> 10n = 125-5 = 120

=> n = 120/10

=> n = 12

so, the numbers are 5*12 and 5*(12+1)

=>  5*12 and 5*13

=> 60 and 65
