Question

4)a) Write three consecutive multiples of 5 ?
!b) If x is the smallest number in three consecutive multiples of 5 ,which are the other
numbers ?
!c) If the sum of three consecutive multiples of 5 is 135, find the numbers ?​

Answer 1

Answer:

a)45,50,55

b)it can be any no. such as 15,20

c) suppose the smallest number is x

then x+x+5+x+10=135

3x+15=135

3x=135-15

3x=120

x=120/3

x=40

then, other no. is x+5=40+5=45

third no. is x+10=40+10=50
