Question

The sun of three numbers is 40. The second number is 6 more than the first. The third number is 1 less than 5 times the first. Find all three numbers.

Answer 1

first n = 5

sec n = 11

third n = 24

Explanation:

40-6+1 = 35

35/7 = 5

1st no = 5

2nd no = first + 6

= 5+6

= 11

3rd no = 5(first) - 1

= 5(5) - 1

= 25-1

= 24

double check total = 1st + 2nd + 3rd

= 5 + 11 + 24

= 40
