Question

the sum of three consecutive multiples of 5 is 165. find the numbers. ​

Answer 1

Answer: 50 , 55 , 60

Step-by-step explanation:

Suppose the first number be p

Hence the second number is p + 5

Hence the third number is p + 10

⇒ p + p + 5 + p + 10 = 165

⇒ 3p + 15 = 165

⇒ 3p = 165 - 15

⇒ 3p = 150

⇒ $\bf\huge p = \frac{150}{3}$

⇒ p = 50

Numbers = 50, 55 , 60

Answer 2

Answer:

let the first multiple =p

let the second multiple=p+1

let the third multiple = p+1+1 =p +2

now ,

5p+ 5(p+1) +5(p+2)

5p+5p+5+5p+10

5p+5p+5p+5+10= 165

15p+ 15. = 165

15p. = 165-15

p. = 150/15

p. = 10

now . the three multiples are =

50,55and 60.

Step-by-step explanation:

check 50,55 and 60 are the consecutive mulpiles of 5

so after adding we get 165

so the answer is correct

50

55

60.
