Answer 1

Answer:Let the number be X

X + X + 7 + X + 14 = 357

= 3X = 357 -21

3X = 336

X = 112 Ans.

Step-by-step explanation:

Answer 2

Answer:

112

Step-by-step explanation:

Let us take three consecutive multiples of 7 as,

7x,(7x+7),(7x+14) [x is a natural number]

7x+(7x+7)+(7x+14)=357

⇒21x+21=357

⇒21(x+1)=357

⇒

21

21(x+1)

=

21

357

[Diving both sides by 21]

⇒x+1=17

x=17−1

x=16

Hence, the smallest multiple of 7 is 7∗16=112
