Question

3. The sum of three consecutive odd numbers is
20 more than the first number among three. What is
the middle number?
(a) 7
(b) 8
(c) 12
(d) 9​

Answer 1

Answer:

(d) 9

Explanation:

Let the consecutive odd numbers be x, (x+2) and (x+4).

According to the Question

x + x + 2 + x + 4 = 20 + x

3x + 6 = 20

3x - x = 20 - 6

2x = 14

x = 14 ÷ 2 = 7

Hence, the 1st no. = x = 7

the middle no. = x+2 = 7+2 = 9

and, the last no. = x+4 = 7+4 = 11
