If the sum of 3 consecutive integer is 210, then the sum of the two smaller integer is-
Solution
Correct Answer: Option A
Let,
Three consecutive integer is, x - 1, x, x + 1.
ATQ,
x - 1 + x + x + 1 = 210
⇒ 3x = 210
∴ x = 70
The sum of the two smaller integer is :
x - 1 + x
= 70 - 1 + 70
= 140 - 1
= 139
Three consecutive integer is, x - 1, x, x + 1.
ATQ,
x - 1 + x + x + 1 = 210
⇒ 3x = 210
∴ x = 70
The sum of the two smaller integer is :
x - 1 + x
= 70 - 1 + 70
= 140 - 1
= 139
